Telegraf monitoring for Solr Cluster

[Walter Underwood <wu...@wunderwood.org>]

I’m still learning Telegraf/InfluxDB, but I like it so far. Does anybody have experience adding simple URL-based probes? For example, I’d like to graph this for each collection.

http://mycluster:8983/solr/mycollection/select?q=${query}&rows=0&wt=json" | jq -r .response.numFound

And this for each core. The script to get the nodes and cores is some scary bash code, I probably should have done this in Python.

curl -s "http://$url_frag/${cores[i]}/replication?_=1535148863458&command=details&wt=json" | jq -r '.details.indexSize' | cut -d ' ' -f 1

The CPU and disk monitoring was easy to set up.
