Offers more than you think
We've used the software to detect layer 7 attacks, unearth issues we didn't realize were happening and gives us end to end insight into our stack.
The system is highly intuitive to use. It is faster than other solutions I've used on the market and has a huge library of 3rd party plugins to get more from the system. It is easy to create scheduled searches, dashboards, reports etc. but there are a number of additional plugins (at an extra cost) to help with security, single pane of glass and metric collection.
It offers challenges for a decentralized working model. Where Splunk is centrally managed, it is easy to ensure that best practices are maintained. Where the system is opened up for an entire department to utilize and on-board their logs, it becomes more difficult. However, with some creative thinking and good process, this issue can be overcome.
Splunk is a great solution for SIEM and also for monitoring your infrastructure
We needed a way to monitor our internal environment and start to be more proactive with issues, so we started sending all of our logs to Splunk and we we able to get insights we did not know we needed. It is a great solution and they are constantly innovating.
Splunk makes it easy to search through various data including logs. In the past I have had to pour through logs in order to find the one lines among the 100 of thousands of lines. Splunk allows me to search through those logs in a matter of seconds vs the hours it used to take.
Most of enterprise setup is done through the command line. It would be nice to have cluster configuration (index creation) as part of the UI.
I have worked with dozens of companies to implement Splunk. My experiences have bee overwhelming positive.
When you need to store, correlate, and search large amounts of data, especially System Log data, there is no tool that even comes close to Splunk. It's power and flexibility is amazing.
Very expensive. Difficult to implement until all moving parts are understood. Steep learning curve for beginners.
Best tool for Distributed logs data analysis
We have several micro-services deployed in production which require to lookup application access as well as server logs and analyze data for their usage. We created several reports/charts for visualization. We use splunk as security logs tool to see the firewall traffic, tracing any vulnerable access, any database related crash ..etc.
It helps easily to find issue and fixed quickly by black listed in system.
Splunk Enterprise is best tool to analyze the data based on different visualization. It help us to lookup distributed logs for micro-services . It enables field based lookup. For complex logging, we can use search query using expression. We can create multiple reports/charts for visualization such as a pie or bar chart for our data. Best feature what i like , We can visualize our search results and share them with others using dashboard panels. If Already have a dashboard, we can add a new panel from a report, clone from another dashboard, or add a prebuilt panel. Fully customization available. Interfaces is very flexible. We export it in different formats, or refresh it to visualize the newest data. Online Support is available through different community.
Search query builder is fully based on technical. for Non technical users, its really difficult to lookup logs. Sometimes, error thrown by query builder is more difficult to understand. Deep Learning is required to use splunk for production data. For Large application installation, it need to manage more.
Everything on every point is under your control.
Splunk Enterpise is the best security information and event management tool ever. It allows you to see far most end point of your system, everything stays under control.
The fature of scrpint/coding your own app inside the Splunk is very useful. I developed a lot of dashboards for our infrastructure, customized alarms, email notfications helps you to see what is happening in the system. It definetely deserves the money our company have had paid.
When you have a real big infrastructure, Splunk user interface gets a bit slow. Waiting for search results a bit annoying.
An excellent tool fol log analysis
Splunk is a great enterprise-class tool for log analysis and troubleshooting of IT systems.
Its graphics capabilities allow you to easily see trends that would otherwise go unnoticed.
With a single click, you can retrieve information dating back months ago.
Splunk is able to handle any type of input file and this allowed us to get very rapid prototyping cycles.
Compared to the competition, it has integrated AD authentication, which fits in perfectly with our corporate security.
The software is very fast, even on second-tier hardware.
The license fee is a little too high.
Some sections of the support site contain outdated information.
Since the Splunk syntax has changed over the years, it's quite easy to find information that is no longer relevant.
The "basic" charting options are somewhat limited, and the "advanced graphic" syntax requires a charting guru.
great insights from system logs
We are using extensively to monitor production jobs and production server. We have setup splunk Jobs to continuously monitor space , files on our server. Automatic emails are triggered if space is not available as expected. This helps to take proactive action and avoid production failures. Splunk is also used to monitor files received from various sources. Our jobs requires multiple files to run the process. We have setup splunk jobs to monitor the files and if any file is not available we are alerted using emails
Various insights are derived from otherwise neglected system and process logs. Library of functions is readily available to read the logs , perform string operations and scan the file.
Information can be represented using numerous charts , bars and graphs. Very useful in production monitoring and alerting using email option
I feel debugging is difficult. drop down or drag and drop functions should be made available because it's difficult to keep track and remember syntax of functions and it's usage.
Excellent tool for logs & data anlaysis
Worth the Learning Curve
As a software engineer, Splunk helps me debug issues in my microservice applications. The Splunk forwarders are efficient and quickly collect logging from multiple server instances. The timestamp resolution is precise making it easier to track down race conditions. The reporting and pivot tables are powerful ways to visualize frequency of api calls once you learn the syntax.
Splunk forwarders that collect the data from applications can sometimes hang and need to be restarted. The amount of traffic that can be collected has maximum caps based on your subscription.
A powerful log aggregation solution with immensely useful tools built-in for popular applications.
- Free to use for small 500MB or less daily ingress, quite nice for small use cases and learning
- No development work required to deploy and provide value.
- Deployment flexibility: client agents are available to use, or clientless configurations for multiple OS platforms. It's also very easy to deploy, not just flexible. its a very simple affair.
- Segmentation of logs: You can create separate instances of of logs to aggregate, based on organization needs. And those instances can have their own individual storage policies to optimize consumption of storage resources.
- Configuration design: Thoughtful and mature documentation and design of the application regarding enterprise-class scaling on network storage.
-POWERFUL tools: The user interface lends itself to learning more about your organization from the logs you collect, through metrics of trends of the logs being gathered. There are also specific modules/add-ons for popular applications to provide more value and event-based monitoring, all without having to develop in-house dashboards and intelligence of those logs.
- Customization: You can create your own queries of logs, and event-based alerts.
- Web-based GUI that clean is powerful
- Sales/Technical Reps are top notch in fielding questions and evaluating environment for deployment. They were extremely helpful in helping our organization develop procedures and scaling our environment for expansion with our existing infrastructure.
- Price: This product is not free for more than the minimal use. Pricing can be very expensive, relative to open source offerings. That is the trade-off you pay for not having in-house development of open source offerings. As this product is priced based on gigabytes of indexed logs, it is important to understand the scope of licensing necessary for your environment to determine if it is a good fit for your organization.
- Watch your saved queries and hardware resources: Users have the ability to create and save queries. Like in database queries, some are more efficient than others. Large inefficient queries can be very resource-intensive. If you notice slowness in day-to-day queries, or navigation in the UI, or resource use in contention, keep an eye on saved queries and user practices.
Query your log statements for your production apps in REAL TIME to triage and monitor performance
XRAY vision on your production instances. Every day we code our applications so that we will be splunk friendly with our app log statements. For example "featureX=value" allows you to query for every customer that engaged with featureX.
Splunk allows us to see exactly what is going on in production! I work on commerce for a fortune 100 company, and we use Splunk to monitor our apps in real time. Splunk gives you the ability to perform queries like you would with SQL against your log statements in real time. You will learn that you can place strategic log statements in your code that allows you to identify situations in production and be proactive at solving them. For example, you can log your customer's session cookie ID, and track any given customer's activity on your website via your app logs. It gives you dials and charting capabilities to monitor even the slightest drops in customer activities due to flaws in code or slowing network calls.
PRICE. The software is so powerful, and they seem to leverage this in the pricing of the licenses.
Overall, it is a very good monitoring tool for an support team and developers for doing root cause analysis.
Splunk Visually represents the logs mainly from production servers in the web UI .
People who Usually has no access to logs in production servers, will access the logs through splunk UI with very simplified and friendly search query.
It has lot of features like you can query for particular date and time range with specific characters. The search engine is very fast which will bring the query response effectively.
we can access all types of logs including XML and JSON.
we can create a custom dashboard with custom query for each projects and can relatively trigger the email to the support team in case of any issues.
This tool is boon for production support team in any enterprise company.
Licensing cost is quite higher for enterprise usage.
Query response time will be slow when you are searching for relatively longer history(Eg. 3 months old data)
Finding Splunk Before Splunk Finds You
Splunk is more than a tool or a product, it is a big data platform. Splunk can be used as a simple log aggregator all the way to a Big Data engine to find efficiency in operations of the Internet of Things. Splunk is less about its abilities, and more about your imagination about what you can do with Splunk. That is the beauty of the platform. Splunk shines in providing operational intelligence about systems and processes. Finding out how your systems are operating, how your processes are functioning leads to quick resolution of problems and points to where budgets are best spent.
Splunk is deceptively easy to set up and use. But like learning to play chess, you can learn the moves in half an hour, but take a lifetime to master. Splunk quickly provides value, but requires imagination and creativity as well as wide ranging knowledge of systems and processes to move to the next level. Not every organization needs that kind of talent to get a great return from Splunk, but the companies who compete and win will.
Best Tool for Monitoring Purposes.
As a user of Splunk, we generally used to monitor the log provided by the server clusters belonging to a tool called API Connect. As the logs are stored in Splunk, we tally the transaction count from API Connect tool and filter the log search in Splunk with a particular search query. We can download the logs of particular time and date of API Connect servers in case of transaction count issues. We create a dashboard for all the individual API's transaction count in terms of total transaction count of all API's. In this way, it makes our work easier to find out which API has the highest transaction count. We even use Splunk to know the state of the machine. Reports generated by the Splunk helps us to find out the API with the highest response time. In this way, Splunk makes our work a lot easier as it is very fast and highly secure.
1) Accepts multiple data formats like CSV, JSON, XML
2) Does the hard work for us i.e converting machine data to a human-readable format.
3) Can create customized alerts to serve our business purpose.
4) Searching on the based on queries is pretty simple.
5) We can create dashboards to analyze and visualize our search results.
6) Can export the log content to our Personal computers.
7) Setting up plugins and integrating with any tool that needs monitoring is pretty easy.
8) Technical support for the Splunk is very quick as they have a dedicated staff for that.
I did not find any flaws with this software.
Great for log analysis
Splunk has been key in sever major issue root causes by analyzing logs and from that being able to build reports and determine causes of issues. In addition being able to trend and look for the data in the many logs is very helpful.
We use this tool primarily as a repository for syslog messages for infrastructure. It allows us to quickly analyze the logs and patterns to determine issues based on patterns. In addition it alerts very well from text based trigger alerts. These features are very easy to use and dependable.
I do not have any cons for this software. Mainly as a user it does exactly what I need it to do with no overhead and confusing interfaces.
Great log analysis software
Integrates with almost all the software seamlessly..where there is a software application that produces log, splunk can be easily integrated.
Gives very powerful insights into the logs
Alerts can be setup on the logs, and notifications sent out which is great again for managing the health of your application
The query language, though powerful, has a learning curve. Particularly as one goes towards complex queries. If it could be made closer to natural language, it would be so much smoother to learn. Hope that will happen sometime in future.
Software is fantastic once you get it fed the data. Setup can be a bear.
Software saves a great deal of time tracking down errors and issues in the network. Was able to spot a security issue using the software we might never have even noticed otherwise.
Fast consolidation of disparate logs in an easy to search way for troubleshooting. I can find problems within my organization very quickly. Sales team was very responsive in getting me a trial license to estimate my needs.
Set up takes some time and planning. The Licensing scheme can be pretty expensive and until you've got it up and running it can be hard to estimate how much license you need.
Good enterprise system for security SIEM, monitoring and data aggregation and visualizations.
I've used Splunk for over 8 years and it is my go-to SIEM. There are tons of apps and integrations. Good for correlation and leveraging the Common Information Model will make your life much happier.
The power of it. It's a very good tool that does amazing things. Nothing comes close to it. We used it for full view of data, full transaction. Security appliance consolidation.
There is a learning curve and a new language you have to learn, but it's intuitive and you can pick it up pretty quickly.
A tool that every sys admin needs to have
I'm not sure from where to start in this case.
We use splunk for many things but mostly to analyze the traffic on the network / firewalls. It provides us with a nice overview of what's going on. It makes it very easy to spot spikes on the network and it will provide you also with deep analyzes.
For us it's an indispensable tool, probably the best tool we have.
To search for something is not always easy, however there are a lot of forums online, so finding help is not that difficult.
Excellent logging and troubleshooting tool
As a software quality assurance engineer, I love that I can setup a single dashboard where I can then view the same data from any lane I select from a dropdown. If I see a problem in the Test lane, I can quickly check all of the other lanes for the same issue by simply changing the dropdown value.
Splunk can give you extreme insights into how your systems and software are functioning. Not only is the search very flexible and powerful, the customizable dashboards give a status report at a glance into trends, problems and performance. You can also set up email alerts when errors occur limiting the need to have Splunk opened on your machine all the time.
Splunk has a learning curve. They have extensive documentation but it isn't intuitive and some features are buried pretty deep. We have an onsite expert who holds bimonthly meetings to answer questions in a group forum.
This is the tool every devops should have expertise on!
Made life easier for all SRE/DevOps oncall.
First of all you don't need to login to your servers. Just configure splunk forwarder on all of your server and have peace of mind. During outages you dont have to panic and just rely on Splunk and be sure that you will have your root cause visible in splunk.
Kernel huge page issues, Search head clustering, Index clusetering. These features are as good as costly too. For SHC and IC it does need all same config hosts.
Premium but pricey log management and analytics tool
Having a enterprise-ready centralized logging tool is critical for production success.
Splunk integrates with almost all popular enterprise software products including VMware, AWS, Azure, etc. Most customers use it primarily to do log analysis but it can also perform data analytics for business reporting. The UI is very straightforward and enables you to quickly search through large datasets using SPL. We were able to quickly locate the source of the issues by using Splunk to triangulate logs from several different components. There is a Splunk Cloud version with a free trial if you are aiming to do some integration work and testing. Finally, like all monitoring tools, Splunk offers AI and machine learning for even better predictive analytics.
Splunk is expensive and probably not for smaller startup companies. The pricing is tiered and is subscription-based so if you start to ingest a lot of data, look out. It can eat into most of your IT budget and Splunk by itself doesn't handle all the Day 2 operations that are needed.
One of the best place to check large amount of the logs information.Every companies best tool.
make our business life easy
The best thing about this software is i love its UI part and its dashboard where it provides the logs of all the enterprise application every business which has large amount of the transactions being held are required to maintain this tool and its logging and search frequency are very much loved and dash board has very colourful UI and easily understandable
There is no least about this software but we are looking for some more enhanced featured like optimisation and all
Splunk is great for finding things in server logs
The server logs are all stored in the same location and you can easy subdivide them by application. So different servers or processes or whatever can be in different buckets. This makes troubleshooting easier.
Sometimes depending on far back you are trying to go the product can be a little sluggish. Beyond that nothing.
