Error: Request contained illegal metachars!

[stecino]

Running this on the NRPE client, works fine

./parse_json_generic.sh 'http://localhost:9200/_cluster/health?pretty=true' \'.status\',\'.timed_out\',\'.number_of_nodes\' "green false 4"
'.status'="green" is OK '.timed_out'=false is OK '.number_of_nodes'=4 is OK

command[check_parse_json_threshold]=/usr/local/nagios/libexec/parse_json_generic.sh $ARG1$ $ARG2$ $ARG3$

Running this from nagios server

./check_nrpe -H xx.xx.xx.xx -c check_parse_json_threshold -a 'http://localhost:9200/_cluster/health?pretty=true' \'.status\',\'.timed_out\',\'.number_of_nodes\' "green false 4"

On the client side I see: Error: Request contained illegal metachars!

I found this in the forum

Got rid of the escaping of the single quotes and it worked

You could try the fix that you referenced in the other post which would require you to re-compile nrpe on the client.

Really there is no other solution, I believe it's the \ which are the cause of the problem.

An alternate solution is something like:

Code: Select all

command[check_parse_json_threshold]=/usr/local/nagios/libexec/parse_json_generic.sh $ARG1$ \'$ARG2$\',\'$ARG3$\',\'$ARG4$\' $ARG5$

./check_nrpe -H xx.xx.xx.xx -c check_parse_json_threshold -a 'http://localhost:9200/_cluster/health?pretty=true' .status .timed_out .number_of_nodes "green false 4"

Otherwise I would look at doing something like check_by_ssh
