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
"
