Using Telegraf, InfluxDB and Grafana to Monitor Network Statistics

Two years ago I wrote about how to use InfluxDB & Grafana for better visualization of network statistics. I still loathe MRTG graphs, but configuring InfluxSNMP was a bit of a pain. Luckily it’s now much easier to collect SNMP data using Telegraf. InfluxDB and Grafana have also improved a lot.

RPM Post-Upgrade Scripts

Something different today: Here’s something I learnt about RPM package management, and post-upgrade scripts. It turns out that they don’t work the way I thought they did.

War Stories: Always Check Your Inputs

The extremely irregular War Stories series returns, with an anecdote from 15 years ago, investigating a problem with a web app that only seemed to crash when one particular person used it. Ultimately a simple problem, but it took me a while to track it down. I blame Perl.
