Original GitHub issue: https://github.com/healthchecks/healthchecks/issues/443

As healthcheck can store all tasks durations, it would be possible to display a gantt graph of all past tasks for a given timeline. I would love to check what happened on a given project in the last 24h hours for example. It could look something like this:

What do you think ?

This would be fantastic, I'm monitoring all of my Proxmox Backup Client runs and it would be awesome to see if any are overlapping and causing extra load/latency.

Thanks, this is an interesting idea, but I'm not planning to work on this.

With the current data model, the duration calculation is somewhat expensive (durations are not stored per ping, instead they are calculated on demand by looking up the previous start event). Doing this for a longer timeframe and for many checks (there are accounts with 1000+ checks) would become quite expensive.

This could perhaps be a report that is run manually and infrequently. But I'm not sure if there's enough utility in this to warrant the dev work.
