Exploring the TICK stack

For those of you that have read my blog you probably know I’ve done a series on performance monitoring infrastructure with the help of InfluxDB.

InfluxDB is a part of the TICK stack delivered by InfluxData. All components are open-sourced and available. The TICK stack consists of, Telegraf, InfluxDB, Chronograf and Kapacitor.

This post will do a quick review and some examples on how I have started exploring them in my Performance monitoring project. continue reading

Firmware update HPE Onboard Administrator

In our environment we have several HPE Blade Chassis systems. The chassis is managed with the Onboard Administrator (OA) which consists of one or two management modules.

Like all other hardware these modules have components that needs firmware to run. And firmware needs to be kept updated to fix bugs, add features, new hardware compatibility and mitigate security risks. It’s also a good thing to keep it pretty close to the iLO version updates on your blades as I suspect HPE might not test newer iLO against a lot of old OA version. However I haven’t found that kind of compatibility matrix.

Normally you need to restart the specific hardware after doing a firmware update. This means downtime, but how can you do this on a blade chassis containing up to 16 blade servers running your production load? continue reading
