vSphere Performance data – New vSphere plugin for Telegraf

Recently there was a new release of Telegraf, a monitoring agent from the guys that built InfluxDB. This new version, 1.8.0, comes with a plugin for vSphere which I’m pretty excited about!

Previously I’ve been testing Telegraf for monitoring some Linux VMs and also my InfluxDB servers and the agent works as expected and it’s as easy to use as the other products in the TICK stack from Influx.

If you’ve followed my blog series about building a monitoring solution for vSphere and other infrastructure components you know that I’ve pulled metrics with PowerCLI scripts. With this new plugin to Telegraf I want to see if I can use this as a replacement. ...  continue reading

HPE iLO affects ESXi management agents – hosts in “not responding”

The last months we have had several issues with ESXi hosts going in a “Not responding” status. The VMs are still active and online in this scenario, but the ESXi cannot be managed. This also affets backup as it won’t be able to reach the VMs through the APIs.

Previously we have normally just restarted the management agents on the host and it has been able to connect to vCenter and after this we have managed to migrate the VMs off the host. Lately this hasn’t worked and we have been forced to boot the host with the result of the VMs getting rebooted by HA and eventually started on a different host.

Almost all of our ESXi hosts is HPE servers. We have also seen in many of these cases that iLO (Integrated Lights-out) management has not been accessible or not responsive. ...  continue reading

Exploring monitoring endpoints in the vCenter Server Appliance (VCSA) REST API

For a long time, actually since we migrated to the VCSA in 6.5 last year, I’ve wanted to utilize the REST API in the appliance to have some monitoring of them.

For several reasons I’ve had to put that on hold, one of them being that there seems to be something wrong with the back-end authentication calls. I get authentication errors on certain calls no matter which user I am logged in with (also the vsphere.local admin account).

You’re in!

This month I was accepted as a vExpert for the first time! In total VMware announced 233 new vExperts this summer for their second half announcement in the program.

The vExpert program is not a technical certification. VMware states: The judges selected people who were particularly engaged with their community and who had developed a substantial personal platform of influence in those communities.

I am very proud and honored to be included in this community. I have for a long time consumed the content produced by many of these great contributors and talented individuals and now to be a part of the same is humbling but also a great achievement for me. ...  continue reading

Upgrading to HPE OneView 4.1 – Failed!

After the release of the new and shiny version 4.1 of HPE OneView we have tried to upgrade one of our (smaller) OneView instances.

The update process is usually quite straight forward and it gets better in every release. The upgrade to 4.0 from 3.x had some issues with certificate handling post-upgrade, but it was manageable.

The upgrade from 4.0 to 4.1 should not be affected by the same so I had great hopes about a smooth upgrade. ...  continue reading
