Agent for Monitoring Linux Operating Systems

Agent for Monitoring Linux Operating Systems

There's already a Windows Agent in the works for SAM that addresses most of the limitations associated with Agentless monitoring of Windows hosts. What about an Agent that addressed the same/similar limitations for Linux/Unix operating systems?

Yes...we need it. (linux, AIX, HP/UX, possibly solaris)

In for a penny, in for a pound. If you guys do it for Winders then you certainly need to do it for systems that you have far less visibility into such as Linux/Unix etc.

I'm deeply DEEPLY conflicted about agent-based monitoring. On the one hand, it bypasses a lot of the issues around security, polling frequency, etc.

On the other, in every implementation of agent-based monitoring I've seen (two different Tivoli installs, BMC Patrol, NetIQ), the agent-to-staff ratio has been about 1,000 to 1.

So I'm worried about what this will mean for skin-and-bones monitoring teams that only survive because agentless has such dramatically lower staff costs.

That said, IF you have agents for Windows, you absolutely need to have them for Linux (Centos/RedHat and SUSE if you need specifics) along with AIX, and HPUX. Solaris and Tru64 are nice-to-have's after that.

I have lived that world...in a large environment you need to monitor and automate as close to the source as possible otherwise your management platform is having to do all the work.  You need to switch to a management by exception model.  Only send the exceptions up to reduce all the noise and traffic.

Leon Adato; I would certainly agree with your concerns as I have had those problems problems as well.  My expectation is that using the agent will be a new option and not the only way to do things.  If that is the case you can pick and choose to use it only when it makes sense.

An agent is a quick fix for companies with the Network ACL rule of deny any any as the standard! My company chose SolarWinds as our enterprise standard but as we rolled it out to our environment we were plagued by some business lines where the IT folks do things a little differently. My company acquires companies now and then and the systems are rarely integrated without a ton of pain and drama. This would allow us to roll out the standardized monitoring solution (SolarWinds and all of the integrated apps) on day 15 (since we have a 2 week lead time on a Network ACL implementation) until the full ACL for agentless monitoring can have all the ports agreed upon.

Having the agent option gives you tools that you may not otherwise have.  I'd rather have the option available to use than not have it. 

I know here I would use it without hesitation.

An agent for UNIX/Linux would be amazing. ONE BIG request would be to differentiate between the actual disk usage and the reserved space. Another request is to have it so the agent does not need to run as root.

I have been posting to Support and Sales about this ago.

The biggest issue for our company when using your products were:

2) Fake alerts due to net-snmp on Linux not sending complete process or other tables resulting in fake alerts (i.e. imagine packet loss). A Linux agent with TCP communciation to the monitoring server will resolve this.

1) We need to scale quick and automate stuff including adding and removing hosts from monitoring. It would take time to automate adding/removing nodes and assigning them templates. It would have been much better if we can install an agent on every node then the node to also have a configuration which specifies which templates to be assigned to it. Then we also need one more thing - a command to remove the node from monitoring and voila - we can easily scale our monitoring to cover hosts running on the cloud behind NAT.

Of course you will also need to change a bit your pricing schema - i.e. pay by node would fit nice.

Many companies will be able to use you when on the cloud and you know a lot of companies run their software on private and public clouds now or have this intent.

I would love to see something around management of Solaris Containers. Kind of like what the Virtualization tab does for VMWare but for Sun Solaris. This is a huge issue for use as we don't have an easy way of relating containers to LDOMs to physical hardware. Being able to easily see this and to be able to set alerts based on dependencies would be great.
