+
+# Note
+
+You have to ensure that you can run the `passenger-status` command under
+telegraf user. Depend on how you install and configure passenger, this
+maybe an issue for you. If you are using passenger standlone, or compile
+yourself, it is straight forward. However, if you are using gem and
+`rvm`, it maybe harder to get this right.
+
+Such as with `rvm`, you can use this command:
+
+```
+~/.rvm/bin/rvm default do passenger-status -v --show=xml
+```
+
+You can use `&` and `;` in the shell command to run comlicated shell command
+in order to get the passenger-status such as load the rvm shell, source the
+path
+```
+command = "source .rvm/scripts/rvm && passenger-status -v --show=xml"
+```
+
+Anyway, just ensure that you can run the command under `telegraf` user, and it
+has to produce XML output.
