Index out of range

[morkster]

When I run both the executable or the docker, I get the below error messages on my node:

INFO[0002] Collecting process_stats for 192.168.7.42:7125 panic: runtime error: index out of range [-1]

goroutine 22 [running]: github.com/scross01/prometheus-klipper-exporter/collector.Collector.Collect({{0x91c0a0, 0xc0000dea00}, {0xc0000ce1f8, 0x11}, {0xc000108f00, 0x7, 0x8}, {0x0, 0x0}}, 0xc0000bc7e0) /root/klipper-exporter/prometheus-klipper-exporter/collector/collector.go:61 +0x612e github.com/prometheus/client_golang/prometheus.(Registry).Gather.func1() /root/go/pkg/mod/github.com/prometheus/client_golang@v1.19.1/prometheus/registry.go:455 +0x105 created by github.com/prometheus/client_golang/prometheus.(Registry).Gather in goroutine 9 /root/go/pkg/mod/github.com/prometheus/client_golang@v1.19.1/prometheus/registry.go:466 +0x568

Any idea what I should do to resolve this?

Similar to the other issue, can you run the following to get the raw API response

curl http://klipperHost/machine/proc_stats

From the error it seem like is getting an empty result.

Thanks, this is odd, the direct API call is returning the expected result, but when your running the collector it appears to be getting an empty result. I'll need to add some more checks in the code to catch and report the error in more detail.
