127.0.0.1:3000: socket: too many open files

[JanKraljic]

Reporter is not closing connections to the Grafana, after max open files is reached (usually 1024) starts returning Code HTTP 500 Internal Server Error . It means that after 1024 is reporter not usable.

lsof -p

grafana-r 7654 root    5u     IPv4 38595998      0t0      TCP localhost:51240->localhost:3000 (ESTABLISHED)

x1024

Reporter output: http: Accept error: accept tcp [::]:8686: accept4: too many open files; retrying in 1s

Grafana Version: 7.2.2 Reporter GIT version.

• It there any parameter to force closing connection streams after PDF is read?
• Any other workaround (increase max open files does not count)?

Today I have faced the same problem. Temporary added a job to restart reporter service once a day.

My solution：Modify the api.go file

First, add the code to import

Then add the following code to the GetDashboard method

Add the same code to the GetPanelPng method

Finally, recompile and install grafana-Reporter

The above is my solution, I am not sure whether it will cause other adverse effects
