Layered configuration

Since SNMP can be integrated with many services, it may be handy to split configuration between several files, each belonging to different packages and teams. For example, you may setup generic SNMP configuration in common pillar file, and it will include:

snmp:
  conf:
    settings:
      logconnects: false
      sysServices: 72

Whereas team, that wants to monitor GPFS with SNMP on the same cluster will add this pillar file to their package:

snmp:
  conf:
    settings:
      master: ['agentx']
      AgentXSocket: tcp:localhost:705
    rocommunities:
      - gpfs
    mibs:
      GPFS: salt://gpfs/files/GPFS-mib.txt

To utilize this ability of layered configuration, you can modify snmp/conf.jinja file in following manner:

# Generic configuration:
{% set conf = salt['pillar.get']('snmp:conf', {}) %}

# Imagine you have team_names list which consist of packages provided
# by set of independent teams inside your company:
{% for team in team_names %}
{% set conf = salt['pillar.get'](
    team + ":snmp",
    default=conf,
    merge=True)
%}
{% endfor %}

# Afterall there might configuration specific to current deployment in separate pillar file:
{% set conf = salt['pillar.get'](
    "user:snmp",
    default=conf,
    merge=True)
%}
