Used to format the message to return can include text as well as special keywords which will include information from the checks.
To add a keyword to the message you can use two syntaxes either ${keyword} or %(keyword) (there is no difference between them apart from ${} can be difficult to excpae on linux).

Possible values are:
Key Value
count Number of items matching the filter. Common option for all checks.

The available keywords are:
Key Value
host The host name or ip address (as given on command line)
ip The ip address name

recv Number of packets received from the host
sent Number of packets sent to the host
time Round trip time in ms
timeout Number of packets which timed out from the host
perf-syntax (CheckNet, check_ping)
Performance alias syntax.
This is the syntax for the base names of the performance data.
Possible values are:
Key Value
host The host name or ip address (as given on command line)
ip The ip address name
loss Packet loss
recv Number of packets received from the host
sent Number of packets sent to the host
time Round trip time in ms
timeout Number of packets which timed out from the host
host (CheckNet, check_ping)
The host to check (or multiple hosts).
total (CheckNet, check_ping)
Include the total of all matching hosts
hosts (CheckNet, check_ping)
The host to check (or multiple hosts).
count (CheckNet, check_ping)
Number of packets to send.
