Check status of Seafile server

Seafile Server
1

Hey,

I would like to implement a dead man’s switch for Seafile: every few minutes, my server running Seafile should contact another server (in my case: https://healthchecks.io) that it is still alive. When this report does not happen, the second server will contact me.

For that, I need a reliable way to check whether Seafile server is working properly. Do you have any ideas how to accomplish that?

Best
Sebastian

Can’t you use the snippets on the linked website?

Actually, I wanted to have a check whether the Seafile server software is still running properly (in case of a software freeze, for instance).

For now, I am using systemctl is-active seafile.service. No idea whether it catches all kinds of errors but it serves its purpose for the moment.

Just in case someone else needs a similar solution, here is the script which cron run every 15 minutes:

if [ “systemctl is-active seafile.service” == “active” ]
then
curl --retry 3 https://hchk.io/xxxxxxxxxxxxxxxxxx
fi

BHey BayerSe,

A while ago I found out that checking Seafile or Seahub’s systemd service is not enough, so I used the API functionality together with a Nagios official plugin. This http plugin (called check_http) can run locally (or from a remote Nagios server)

/usr/local/nagios/libexec/check_http -H my.seafile.local -p 8000 -u ‘/api2/ping/’ -s pong
/usr/local/nagios/libexec/check_http -H my.seafile.local -p 8000 -u ‘/accounts/login/’

This check_http plugin can be obtained from Nagios Plugins | Nagios Open Source or as a package from repositories (depending on your OS).

If the plugin detects a non-OK state the exit code will be higher than 0 (1=warning, 2=critical,3=unknown state)

Have fun, Jorgen

Thank you! That is very helpful. Setting up a Nagios server is probably too much, but maybe I can use it by some other means which I will figure out.

If you don’t want to install nagios, use bash:
[[ $(curl -Ss "https://my.seafile-server.net/api2/ping/") == "\"pong\"" ]] && exit 0 || exit 1
If curl doesn’t trust your certificate, use -Ssk as options for curl (instead of -Ss).

The exit code is 0 if the server replies as expected, otherwise it will be 1.

Cheers, Bernie_O
