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 …

The schedule builder for VMworld Europe 2018 in Barcelona is finally live and sessions can be scheduled. For the first time I will have a session at VMworld, as one of the vBrownBag/VMTN community sessions, and I'm really excited about this. It is very cool that these community sessions are available in the schedule …

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 …

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 …

Following up on my last post on Limiting disk i/o in vSphere we will now see how to automate this. First off we need some way to identify what limit a specific disk should have. You can do this in multiple ways, you could use an external source, you can use Tags or as we've done, Storage Policies. All our VMs and VMDKs …
