curl, json and -d query

[nov1c3]

Hello,

I'd like to monitoring the value of count (if it's 0 then trigger CRITICAL) from the following curl command:

Code: Select all

curl -u login:pass 192.168.100.9:9200/events/_count?pretty=true -H 'Content-Type: application/json' -d'{"query": {"range": {"recordTime": {"gte": "now-12h"}}}}'

{
  "count" : 2073,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  }
}

I tried several check_json plugins, but I can't figure out how to pass -d'{"query": {"range": {"recordTime": {"gte": "now-12h"}}}}'.

Any tips would be greatly appreciated. I'm using Nagios Core 4.4.6 under Debian 10.

Thank you.

jq is pretty dope IMO. Widely available on many linux distros via the package manager. Easy to stuff in a Bash script. Feed your cURL output into it, do a simple -eq evaluation afterwards.
