Saltstack: Jinja error: How to get SLS file name and line number that contains the error

saltstack

I get this error message after refactoring my sls files.

I created new sls files and use the include directive to have more modular formulars.

salt:/srv # salt-ssh w123 -v state.sls monitoring
Executing job with jid 20160512154840991359
-------------------------------------------


[ERROR   ] Rendering exception occurred :Jinja variable 'system_home' is undefined
[CRITICAL] Rendering SLS 'base:monitoring.service' failed: Jinja variable 'system_home' is undefined
w123:
    - Rendering SLS 'base:monitoring.service' failed: Jinja variable 'system_home' is undefined

How can I get the SLS filename and line number where the variable is undefined?

This one of things kills me in regard to SaltStack! Unclear error messages, and it doesn't tell you where is the problem!

Anyway, check that post "Debugging Salt and Salt States", try to debug the error using "salt-call".

SaltStack | How to assign the shell output from cmd.run to Jinja variable

I think the main problem is that load_avg from cmd is not a number but a string and you have to convert it. Using load_avg|float (or even load_avg|int) like this works:

{% set load_avg = salt['cmd.shell']('uptime | sed "s/.*load average: //" | cut -d " " -f2 | cut -d . -f1') %}
{% set threshold = 1 %}

check_load_avg:
  cmd.run:
{% if load_avg|float >= threshold %}
    - name: echo 'Load average is HIGH. load_avg={{ load_avg }}, threshold={{ threshold }}'
{% else %}
    - name: echo 'Load average is normal. load_avg={{ load_avg }}, threshold={{ threshold }}'
{% endif %}

Output:

----------
          ID: check_load_avg
    Function: cmd.run
        Name: echo 'Load average is HIGH. load_avg=1, threshold=1'
      Result: True

              stderr:
              stdout:
                  Load average is HIGH. load_avg=1, threshold=1

With threshold=5:

----------
          ID: check_load_avg
    Function: cmd.run
        Name: echo 'Load average is normal. load_avg=1, threshold=5'
      Result: True

              stderr:
              stdout:
                  Load average is normal. load_avg=1, threshold=5

EDIT:

You can get the load average using directly the salt module status.loadavg:

# salt-call status.loadavg
local:
    ----------
    1-min:
        0.12
    15-min:
        0.31
    5-min:
        0.25

In jinja:

{% set load_avg = salt['status.loadavg']()['1-min'] %}
