Re: When do you go for agent-based and when do you go for agent-less monitoring?

Ramkumar Devanathan

Hi Lindsay, thank you for the valuable comments/guidance. This helps set the context of this blog post - my focus has been on the monitoring approach itself - which approach to use, and when both approaches become useful.

 

Yes with the suggestions you have provided, configuration complexity will be reduced and this is useful feedback to pass on to the product engineering team (which I have done already). Watch this space for updates in this respect.

 

Looking forward to further discussions with you, and hopefully we can get to meet soon :)

What I'd like to see is a management platform that lets me set consistent policies, regardless of if agentless or agent-based monitoring is used.

 

E.g. I could set a disk space policy for a node, and the management server would be intelligent enough to know if that node has an agent installed or not, and would then use whatever monitoring method made sense. Then if I later tried to assign a policy that needed an agent, the system would be intelligent enough to deploy an agent. But if the policy needed to be agentless (e.g. remote monitoring if a port was open), then it would automatically be done in an agentless manner.

 

I'd like to do this all from one console, with consistent terminology and interface. Not the mishmash of Operations Manager + SiteScope, but one consolidated tool that takes the best of both products. I'd also like this to be consistently licensed too, so customers could seamlessly switch between agents and agentless, depending on the requirement.

 

I'd also like the agents to be stable, which HP Operations Agent have not been. Using the latest publicly available versions + patches of OMW, NNMI and Operations Agent, the opctrapi process keeps restarting. This is using the latest versions, using the HP recommended integration method. That's a big reason why people don't like agents - they're just not stable, and then rolling out updates is a real pain.

 

Oh and agent-based is the wordcloud on the left.
