varnish-6.2.1 revision 9f8588e4ab785244e06c3446fe09bf9db5dd8753 - prometheus_varnish_exporter
v1.6 (0855dcb)
I encontered a issue when i reload varnish, the output of metrics is a 500 Status code with this message:
http://myvarnishhost:9131/metrics
An error has occurred while serving metrics:
210 error(s) occurred:
* collected metric "varnish_backend_beresp_bodybytes" { label:<name:"backend" value:"es" > label:<name:"server" value:"unknown" > counter:<value:0 > } was collected before with the same name and label values
* collected metric "varnish_backend_pipe_in" { label:<name:"backend" value:"tod" > label:<name:"server" value:"unknown" > counter:<value:0 > } was collected before with the same
....
- If i restart the exporter, i get the same response.
- If i wait 5~10 minutes sometimes the response is 200 with a normal metrics
- if i restart varnishd the metrics works fine
In the production environment is not possible restart varnish becaus we lost all cached data.
I wait for you help. Thanks a lot!
