usage_description="
Run a command against each Pingdom check
All arguments become the command template
The command template replaces the following for convenience in each iteration:
{id} - with the check id <-- this is the one you want for chaining API queries with pingdom_api.sh
{name} - with the check name
eg.
${0##*/} 'echo check id = {id} and name = {name}'
For real usage examples, see:
pingdom_checks_outages.sh
pingdom_checks_latency_by_hour.sh
