Problem with building

[brushek]

I'm trying to use this adapter, but can't build it:

go get: warning: modules disabled by GO111MODULE=auto in GOPATH/src;
        ignoring go.mod;
        see 'go help modules'

The adapter use go-modules. From your logs, it seems that Go disable it. Can you try with: export GO111MODULE="on"

[brushek]

After export GO111MODULE="on" I could compile source code, but then - after running graphite-remote-adapter I get:

./graphite-remote-adapter 
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x78a2db]

the format in promlog has changed, following change resolve problem:

Thanks for the fix! They were included in the main tree.
