Check the status of a sks keyserver entryhttps://github.com/lrupp/tools/tree/master/monitoring-plugins-sks_keyserver
If you are an administrator of a public SKS server (GPG key server), you should check
regulary that your server is in the SKS pool. This plugin for your monitoring server
will help you with that as it queries (per default, URL can be adapted) the public
sks-keyservers.net server for the given hostname and outputs not only if the server
is still in the pool, but also some additional statistics that you might want to
have at hand from time to time.
Please note that the plugin can also output the states of your peers (option: -p),
so you can inform then if they are not in the public pool any more.
Warning and critical levels exist to configure the amount of "good" peers you want
to see your server connected to at any time.
