BigIP Report feedback requested

Want to speak your mind, share some feedback?

The report has been evolving a bit more towards being more user friendly lately. Icons has been added, column toggle, preferences and reset search.

But truth be told, I more or less have no idea who uses the tool and I’ve got no statistics whatsoever except for the feedback I get in the insanely big comment thread on devcentral.

To make it easier for me to make better decisions/priorities about future features, or even to get ideas from you guys and girls, I’d love if you could answer this short poll (no registration is required):

http://www.polljunkie.com/poll/facgco/bigipreport-survey

While the poll is anonymous and the questions is not targeted at you personally it’d nice with an introduction in the last free text question, if you feel like it. 🙂

Any feedback (good or bad) is appreciated, as it always has been.

Thanks!

Troubleshooting IPMI pollers in Observium

Getting temperature readings from your ESXi host in Observium

It always irked me that I was not able to read the temperature of my ESXi host. Lately I renovated a storage space underneath my stairs and moved all my infrastructure to it. Since there is a lot of equipment in the same place and probably could get really hot unless I calibrate my fans accordingly I decided to give it one more try.

This time I succeeded, and here’s how to do it.

This guide probably works at least partly for LibreNMS too.

Intalling ipmitool

First things first. Make sure that you have ipmitool installed, otherwise install it:

Create a user via your IPMI web interface

Verify that you have a user set up with the correct permissions (“User” was enough in my case).

Test the IPMI interface with ipmitool

Then you can test the connection to your IPMI interface with the following command:

What this does is to show the sensor of your chassis using the protocol support used by an IPMI v2.0 RMCP+ LAN Interface.

If this does not work, verify that the port of your IPMI API is 623 (UDP). You can also try a different interface from the following list:

Configuring Observium

Navigate to your ESXi server in Observium, click on the settings button, and the “Properties”. Here, go to IPMI and enter the settings used above.

Troubleshooting Observium

In case you still do not get temperature readings in Observium there is one more trick that you can try.

This command will show you exactly which command Observium is using. Compare the command with your successful attempt from the steps above and attempt to change accordingly.

TLDR;

My mistake was that the IPMI “API interface”  does not necessarily listen to the same port as the web interface. In my case it was listening on port 623 (UDP).

What was yours?
