./check_riak_write.pl --help

Nagios Plugin to check Riak is working and writeable via the HTTP Rest API

Checks:

1. writes a new unique key to the nagios bucket with dynamically generated value
2. reads key back, checking the value is identical to the value generated and written
3. deletes the key
4. records the write/read/delete timings to a given precision
5. compares each operation's time taken against the warning/critical thresholds if given

Control of Riak's n_val for the nagios bucket should be done separately, preferably by pre-creating the bucket with the desired n_val
