Issues when graphing nodes trough passive checks 🙂

Hello!

It is my first post, so I decided to write because I couldn’t find information in the forum about my issue. I’ll try to describe in detail.

So, my issue is related with graphing. I have a lot of graphic nodes working with influxdb and grafana. I have to say that I didn configured this system, Iḿ just fixing missing graphics for several nodes.

All those nodes that doesn’t show the graphs are monitored by a passive checks/scripts, the other that have graphics use active checks.

There is something that I’m missing? I have a lot of time viewing what is wrong but I can’t find the culprit.

BTW: Sorry for my poor english.

Thanks in advance and best regards,

Oscar.

Hello @oamata!

Please provide an example passive check result which doesn’t reach your graphers.

Best,

Hello @Al2Klimov

Thank you for your reply, but I already fixed my problem with graphing. It was that process perfdata was disabled in the passive-check service.

But Iḿ wondering if there is a way to do pings passively to each host.

Best regards,

What is a “passive ping”?

For others hosts I use active monitoring and I can see a graph with the latency to that host issued by Icinga using a ping. So I’m wondering if I can do the same by a pasive check.

Oscar.

Yes, but my question is “what is a passive ping?”

“ping” for me is something you actively do, to see whether there is a “pong”
response.

I ping you, you pong back - success.

I ping you, you don’t respond - fail.

So, unless I actively send a ping request, how is it possible to get a
resonse?

What sort of passive service check could achieve the same thing?

I’m sure that if you can think of what you want the passive check to be,
Icinga can handle it, but I have no idea how that can work without being an
active check.
