munin alert through external scripts fails

I am stuck with munin alerts through external scripts. I followed the guide here(http://guide.munin-monitoring.org/en/latest/tutorial/alert.html#alerts-to-or-through-external-scripts), but it turned out wrong.

contact.test.command >/etc/munin/scripts/sendsms.py /etc/munin/scripts/sendsms.py

munin-limits log shows:

[WARNING] Found ">" at beginning of command. This should no longer be necessary and will be removed from the command before execution.

[WARNING] Failed to close pipe for contact test: Broken pipe

And sendsms.py receives nothing from stdin, which is weird.

Where is the alert info? What's the correct way to write the command?

best is to debug it this way:

su - munin --shell=/bin/bash
/usr/share/munin/munin-limits

You forgot to add [pipe] for your script.

Can use static message like this:

contact.test.command | /path/to/my_python_script.py "something gone wrong!!!"

Or use [vars] supplied by munin:

contact.test.command | /path/to/my_python_script.py "${var:group} ${var:host} ${var:graph_category} '${var:graph_title}'"

I am running alerts based on a python script on my server. To set this up put it into your /etc/munin/munin.conf In my case that would look like:

contact.test.command | /path/to/my_python_script.py

The python script itself is executable by munin. Inside the script I read from Stdin the text that is specified at

contact.test.text some text and ${var:label}

using some of the Munin variables specified at http://munin-monitoring.org/wiki/MuninAlertVariables
