Support can retrieve salient logging data from massive distributed systems in seconds but deployment is not easy.

I've been using Splunk for over 3 years now. The most valuable feature for me is alerting. Using Splunk, production support teams can retrieve salient logging data from massive distributed systems in seconds.

I'd say that some the key/value pair parsing can be a little off and has room for improvement. The deployment is not easy and I've only encountered issues with stability and scalability when on under-provisioned equipment. The initial setup was complex - need to identify source types in advance, and a large deployment with multiple indexers can be tricky. We initially implemented in-house, and then through Splunk themselves to upgrade and improve.

Before implementing Splunk we used an in-house system, but Splunk offered far more to us. Also, their customer service is good and their technical supper is excellent. Our ROI was big!

I'd advise others who are looking into implementing Splunk to get a true Splunk expert - either spunk themselves or a vendor, to do the installation.

It can probably do anything if you tweak it enough but it's not cheap.

Splunk is really good at log parsing events over time. It is quick to drill in and analyze and it is quick to build a presentation layer and automate reporting. I love it for problem analysis and event management however it is not a capacity management tool. 

It can be a cm tool but not a good tool for projections etc. There are many tools that claim to be cm tools but they are usually expensive and miss the basic day to day challenges of capacity management. Eg: excluding backups from day peaks, removing outliers, forward trending, accepting data from any source. Start by getting your key data extracted from reliable sources and other tools.

The charting and presentation layer is impressive and quick. It can probably do anything if you tweak it enough. I would call it a very handy tool but probably not the tool. It is not that cheap either. I have used it personally to analyze big data as well as creating knowledge from some ordinary logging. I then created some pretty cool dashboards but they were more operational dashboards.

I don't think we could afford it as a capacity tool but we can use the data it simplified.

Good product that satisfies our customers
Pros and Cons
  • "The product is good, it satisfies our customers."
  • "The prices are complicated as we operate in a small third-world country."

What is our primary use case?

Our company is an IT service provider. We are resellers of Splunk. One of our clients that we monitor is a laboratory that uses this solution.

Splunk is a change management solution. We use the solution as a log collector, and to analyze and provide alerts from the IT instructor.

What is most valuable?

The product is good, it satisfies our customers.

What needs improvement?

The price of Splunk is too high for our market.

For how long have I used the solution?

Our company has been a reseller of Splunk for less than six months.

What do I think about the stability of the solution?

Splunk is stable.

What do I think about the scalability of the solution?

This is a scalable solution.

How are customer service and support?

We have had no concerns with customer service.

How was the initial setup?

The initial setup of Splunk is somewhat difficult because it was our first time implementing the solution. It was a similar situation to implementing other CM tools like FortiSIEM.

What about the implementation team?

Splunk required two engineers to implement, and we will add another one to maintain the solution.

What's my experience with pricing, setup cost, and licensing?

The prices are complicated as we operate in a small third-world country.

Which other solutions did I evaluate?

We give support for VMware and other technologies. We purchased Splunk because our customers were asking for our services to take control of the implementation from another company.

What other advice do I have?

If you are considering Splunk and you like what you are seeing; my advice would be to go for it.

I would rate Splunk an 8 out of 10.

Easy to configure with user-friendly alerts and good search functionality
Pros and Cons
  • "We can easily configure things as required in relation to our use cases."
  • "From the commercial point of view, they have to bring down their costs."

What is most valuable?

We enjoy the whole solution. It is meeting our requirements, especially the SIM solution. 

The alerts are very user-friendly.

We can easily configure things as required in relation to our use cases.

The search functionality is good. It works like Google. 

Onboarding is quite easy.

The scalability is good.

Product-wise, the performance is good. 

What needs improvement?

From the commercial point of view, they have to bring down their costs. It's a bit pricey right now. The license is quite expensive. 

Much like the SOAR platform, which has security, orchestration, and automation response, all of that should be part of the SIM solution itself. Currently, it is actually separated.  We understand that we have to integrate a SIM with a SOAR platform, however, if they could combine these two products together, that would be ideal. It would make things easy to implement and make more automation possible to avoid false-positive alerts.

For how long have I used the solution?

We've been using the solution for the last four years. It's been a while. 

What do I think about the stability of the solution?

The performance is good. It's stable. There are no bugs or glitches. It doesn't crash or freeze. 

What do I think about the scalability of the solution?

The scalability of the solution is very good. If a company needs to expand, it can do so. It's easy.

What's my experience with pricing, setup cost, and licensing?

The solution can be expensive. It's not cheap.

What other advice do I have?

We are customers and end-users. 

I'd rate the solution at a nine out of ten.

Looks for incidents which could cause damage to a company's infrastructure
Pros and Cons
  • "Splunk has facilitated the correlation of information security logs to look for incidents which could cause damage to the company's infrastructure, as well as financial losses from leaks."
  • "Splunk can improve regex/asset analysis as we do not want to crawl until it is done."

What is our primary use case?

With the use of Splunk, we were able to identify a brute force attack against a "switch" network device. An external attacker attempted to connect multiple times using multiple usernames. Splunk was able to detect these attempts and immediately blocked these attempts.

How has it helped my organization?

Splunk has facilitated the correlation of information security logs to look for incidents which could cause damage to the company's infrastructure, as well as financial losses from leaks.

What is most valuable?

Splunk's ability to receive all types of data and identify it correctly. It obtains a correlation of the logs and identifies incidents.

What needs improvement?

Splunk can improve regex/asset analysis as we do not want to crawl until it is done. I could not find a timestamp for when the log was processed and generated.

For how long have I used the solution?

One to three years.

Fast availability of operational data spread across several servers is nice, but the MES is a complex system.

What is most valuable?

What Splunk calls operational intelligence: fast availability of operational data spread across several servers to prevent or react faster to outages or performance decreases.

How has it helped my organization?

MES is a complex and very critical distributed system here. Production WIP is directly connected to it and ICT is required to provide a continuous availability and very stable performance (line production has a costant speed, software cannot slowdown). Collect operational data from hardware, middleware and application software can potentially improve ICT proactive and reactive tasks.

For how long have I used the solution?

I've ever used it, just studied it.

Which solution did I use previously and why did I switch?

We also use a traditional monitor, and Microsoft SCOM.

What was our ROI?

Every stop or slowdown of the production line means lost of money, e.g. 30% reduction when compared to the current baseline.

What's my experience with pricing, setup cost, and licensing?

Every stop or slowdown of the production line means lost of money, e.g. 30% of reduction compare to the current baseline.

  • "I am satisfied with the support."
  • "The price of the solution could be cheaper."

What is our primary use case?

We use the solution for monitoring systems. We also use it with servers and CG routers from the data center, as well as for collecting the ADL from all networks which are located in our regions of the country.

What is most valuable?

I like that the solution is easy to use and stable. 

What needs improvement?

The price of the solution could be cheaper. 

For how long have I used the solution?

I am currently working with Splunk and have a year's experience doing so. 

What do I think about the stability of the solution?

The solution is stable. 

What do I think about the scalability of the solution?

The solution is scalable. 

How are customer service and support?

Support is at a level one department and I am responsible for managing both IT support and node engineers. 

I am satisfied with the support. 

How was the initial setup?

The solution is easy to install. 

It took half a day. 

What about the implementation team?

We were able to handle the installation on our own. 

There are 40 people responsible for the deployment and maintenance of the solution, four of whom are engineers. There is a computer DE who is responsible for the engineering and a candidate for graduation in 2022.

What's my experience with pricing, setup cost, and licensing?

The solution could be more cost-effective, as we charge our customers the cheapest price. 

The subscription is monthly. 

What other advice do I have?

The solution is cloud-based. 

There are more than a thousand users making use of the solution in our organization, who are connected with us in over 530 different areas. 

I recommend the solution and plan to continue using it. 

I rate Splunk as a seven out of ten.

Stable, good integrations, and works well
Pros and Cons
  • "It has quite extensive support in terms of integration. If you want to do anything, there are tools for that."
  • "Its reporting can be improved. That's the only complaint I have heard. I don't need the reporting part, but I know that other people in the organization need it."

What is most valuable?

I am just a user, and from a user's perspective, it does the job.

It has quite extensive support in terms of integration. If you want to do anything, there are tools for that.

What needs improvement?

Its reporting can be improved. That's the only complaint I have heard. I don't need the reporting part, but I know that other people in the organization need it.

In terms of new features, I got everything that I needed from the tool. If they want to expand the capabilities to different things, they can cover topics besides log aggregation, etc.

For how long have I used the solution?

I have been using this solution for two years. I am not using it on a daily basis.

What do I think about the stability of the solution?

It is stable. We don't seem to have any problems related to bugs. We are very happy with it.

What about the implementation team?

We have our own internal team for its maintenance.

What other advice do I have?

I would recommend this solution. If you are a technical person, it does what you need. If you are not a technical person and you require graphs, that's a different story.

I would rate Splunk a ten out of ten because I have no problems with it.

Which deployment model are you using for this solution?

On-premises
