Monitors
In use
Uptime Robot
https://stats.uptimerobot.com/81NqJuOD8 Monitor sites’ uptime. We have up to 50 monitors for the free plan but I think it is lower now. Sends notifications when a site goes down. You can set it to check https, ping or http every 24 hours down to 5 mins (free plan).
StatusCake
This was being used to monitor uptime for the VPSs. It can monitor sites too. Uptime Robot allows us 50. Using this sometimes for VPS monitoring. Here is our page.
Uptime-Kuma
Hopefully this can replace the others. Now has its own page.
Others
Satoshihost/Uptime
Our own repo in github is now deleted, there are mush easier and more relaible options. Fork of Upptime. We could use this maybe, it includes hosting so no need to use a VPS. The place to turn things on and off took me ages to find. I have a bogus url in there to test that it is working ok but I was getting dozens of notifications from it per day so I have archived the repo, because apparently we can unarchive it again when we want to continue development.
Freshping
This is freshworks service. It gives 50 monitors on the free plan, up to 1 mins interval. Not used yet but may be good to have later.
Datadog
Up to 5 hosts on free plan. This may not be much use for domain monitoring but for monitoring the hosts perhaps. More info should be got! https://www.datadoghq.com/pricing/
BetterUptime
10 free checks in the free plan. https://betteruptime.com/pricing
HetrixTools
15 uptime and 32 blacklist montors for free. https://hetrixtools.com/
Self-hosted
Maybe we can use this when we have too many accounts to monitor for free.
