OpenHardware MUC statistics

OpenHardware MUC statistics

Why? One of my users, namely kikuchiyo, approached me with his idea to determine the distribution of users in his MUC room. The given hypothesis was, that the user count peaks during the weekend. As my general monitoring does not track the user count per room I was fairly interested in the data. Unfortunately ejabberd is not able to export these statistics, thus some custom steps were required. This was a temporary statistics gathering process only.

Nextcloud Munin Plugin

basic idea For a longer period of time I was looking for a Munin plugin to monitor the activity, especially the user activity on my cloud instance. There are some plugins out there, but most of them depend on externally querying the database. With the External API and the server info dashboard Nextcloud itself presents an endpoint to gather data from. This way the database action is handled by the cloud and I can just grab the data from the endpoint.

Let's Encrypt Prosody Cert Hook

Prosody + Let’s Encrypt certificates As of right now Prosody is not able to update a live certificate while running. For the complete update it is necessary to restart Prosody, which is inconvenient. With the telnet console however, it is possible to reload the config such that a changed certificate is updated correctly. The biggest problem lies in reloading all possible locations the “old” certificate is still active in. I use the Prosody Telnet console to invoke a reload, due to the fact that prosodyctl reload is not actually reloading the modules just the config.
