=head1 NAME

snmp__gsa_docs - SNMP wildcard plugin to monitor Google Search Appliance (GSA) document statistics

=head1 APPLICABLE SYSTEMS

A GSA running software version 5.0 or above. See [1] for counters
exported via SNMP. Usage of SNMPv3 is recommended, with AuthPriv,
and the SHA authentication scheme.

[1]: https://developers.google.com/search-appliance/documentation/50/help_gsa/admin_snmp

=head1 CONFIGURATION

Create a "Munin" user on the GSA SNMP configuration, and then use
something similar to the following:

[snmpv3_gsa.host.name_*]
  env.v3username munin
  env.v3authprotocol sha
  env.v3authpassword your-auth-passwd
  env.v3privprotocol des
  env.v3privpassword your-priv-passwd

Please see 'perldoc Munin::Plugin::SNMP' for further configuration
information.

=head1 INTERPRETATION

The graph shows statistics about the documents index and queries per minute.

=head1 MIB INFORMATION

GSA-MIB::docsServed.0 = INTEGER: ..
GSA-MIB::docErrors.0 = INTEGER: ...
GSA-MIB::docsFound.0 = INTEGER: ...
GSA-MIB::docBytes.0 = INTEGER: ....
GSA-MIB::qpm.0 = INTEGER: .........
