Troubleshooting tools?

[benel]

Dear CouchDBers,

A friend of mine has a recurring problem with a CouchDB instance (with a lot of valuable data) when tens of users update data in the same timeframe.

I would like to help him diagnose the problem, but except for some intuitions I could have (too few memory on the server, timeout in view computation, reverse proxy altering the _changes flows), I find it very hard to help him troubleshooting its server.

Are there any tools I could recommend it to help him point to the cause of the massive slow down he faces?

I saw in the new version of documentation that weatherreport is installed with CouchDB. Could it be used for this kind of troubleshooting (even if the instance is standalone). If yes, how can it be used exactly? I found the executable in the Docker container. I've tried to add the location of weatherreport and escript in the PATH, but didn't succeed in running it.

Any help would be greatly appreciated.
