After starting pgscv, although pgscv's status is active, but it gives following error:

 **service":"pgscv","time":"2022-06-23T15:33:32+04:00","message":"system/sysinfo collector failed; invalid input, '': wrong number of values"}**

Also, i connect my database to prometheus and grafana, and in every 3 minute it returns no data, and after 30 seconds i am able to see data means i loose some data. So, I changed restart time to 1 sec, and now after 12 minutes for 2minutes there are not any data repeatedly.

OS: Centos 7
pgSCV Version: 0.7.5
Postgres: 11
Postgres and pgSCV are running on the same host
