ESM setup on CentOS ???

Jump to solution

Dear All,

Can anyone please confirm, if we setup our arcsight production setup on CentOS, then "ArcSight support will be valid or not"

I heard that ArcSight support will not be valid if manager or DB is installed on CentOS, just want to confirm here.

Please advice.

Rgds,

Anwar

Gary, I know the difference between CentOS and RHEL. Theoretical risk of "critical issue" could be easily mitigated by Q&A testing, which is anyway done for any ArcSight product release. And it's up to end user to accept or not accept this risk. Also using RHEL does not guarantee anything by itself, what if this "issue" happen just after you decided not to prolong support for RHEL?

I can repeat, that Logger and ConApp are officially supported to be installed on particular versions of CentOS, so in my opinion it's only a matter of time when the same will be applied to ESM. It really matters for many customers. Many of those I know, don't want to buy RHEL, because they already have something else as an internal standard for linux OS, SLES, for example. So, what would you tell them? "Go and buy couple of RHELs! Don't you have money, huh?" or "Well, this could be easily done with free CentOS, you don't need to have another contract for another linux OS, just accept CentOS+ESM as a complex, solid solution."

I suppose that from point of sales strategy, flexibility (with some minor risks involved) is much better than unbendable, regid position.

AFAIK ArcSight will refuse support for this installation, because it's not a supported plattform.

But I never tried to push my luck...

All supported operating systems are listed here.

Yes that's correct.

The ArcSight Support would not be available for CentOS installation.

But as a suggestion, it'd be better not to use a CentOS installation in a "production" environment.

For all ESM products that running on Linux, only Red hat Enterprise Linux will be supported.  Please refer to the installation guide for more detail information.  Thanks .

That's quite immature and inconsistently from HP side. Logger and ConApp officially support installation on CentOS. Only ESM still doesn't, though 6.x works very well on it and 6.5c even don't complain about unsupported platform during installation. So I hope that soon CentOS support will be added officially. There is no reasonable cause not to do that.

@Ivan, CentOS should not use for production environment because it doesn’t not have an enterprise support like RedHat Enterprise Linux.
 

For example, if user encounter any critical issue with RedHat Enterprise Linux, RedHat will provide a solution / patch update as soon as possible.  If you are running CentOS, you will have to wait for 6 – 9 months before you get the fixed or patch update. 

I am sure many of us ask the questions "CentOS vs RedHat" I found the following post has a good solid answer :: http://unix.stackexchange.com/questions/27323/is-centos-exactly-the-same-as-rhel

//------------------
CentOS is very close to being RHEL without the branding and support. In particular, the library versions are the same, so binaries that work on one will work on the other. The administration tools are the same and configured in similar ways. However, there are a few differences, as the two distributions sometimes apply different minor patches. For example, in this question, it was apparent that RHEL 5 and CentOS 5 apply different rules to identify files under /etc/cron.d.

In other words, at the level of your course, you can treat CentOS and RHEL as interchangeable. But if you needed to look up the precise behavior of a program in a corner of the man page, you may encounter differences.

//------------------

CentOS is very similar to RedHat Enterprise Linux but they are not exactly the same 🙂

We are running ESM 6.5c on CentOS 6.2 and have not had any problems getting support.  Mostly they just ask for logs anyway and when you submit a support ticket, they only ask for the OS (Windows or Linux) not which flavor.

We have been running for a while and have had no problems.

Even the CentOS developers are also the same RedHat developers.

Its just the matter of Support.

Re: ESM setup on CentOS ???

You are correct - its a matter of support. When releasing a product, customers need to know the versions of the supported OS and as a result the development team need to test as much as they can. Its actually very difficult to add a new OS and the time and effort required is actually very extensive. For HP release and support minimum standards it is expected that support is a minimum of 2-3 years for each and every product and platform.

It might be simple to add CentOS since the similarity, but that means we need to do the regression testing on versions and also make sure we provide full support for multiple years going forward. Platform / OS support is a very serious point as upgrading a product is relatively simple, upgrading the OS is much more painful - and as a result we can't just pull the rug from under someone in a short period of time. Its not great.

We recently added SUSE support for CORR based versions of ESM and the Oracle based versions take an age to regression test on the spread of platforms there. We need to speed up releases and do them faster, more efficiently and on a more aggressive cycle - adding platforms will only increase things I am afraid. Not saying we won't add CentOS (actually its quite positive), but just because of its similarity to RHEL, it doesnt make it easier I am afraid.
