Ubuntu agents running 32 bits

MacOS agents in datacenter SCL3
  $ mig-agent-search "environment->>'os'='darwin' AND name LIKE '%%\.scl3\.%%'

Agents with uptime greater than 30 days
  $ mig-agent-search "starttime < NOW() - INTERVAL '30 days'"

Linux agents in checkin mode that are currently idle but woke up in the last hour
  $ mig-agent-search "mode='checkin' AND environment->>'os'='linux' AND status='idle' AND starttime > NOW() - INTERVAL '1 hour'"

Agents operated by team "opsec"

		fmt.Fprintf(os.Stderr, `%s <query> - Search for MIG Agents
Usage: %s -p "console style query" | -t "target style query"

The -p or -t flag must be specified.

CONSOLE MODE QUERY
------------------

The console mode query allows specific of a query string as would be passed
in mig-console using "search agent". It returns all matching agents.

EXAMPLE CONSOLE MODE QUERIES
----------------------------

All online agents:
  $ mig-agent-search -p "status=online"

All agents regardless of status:
  $ mig-agent-search -p "status=%%"

See the output of "search help" in mig-console for additional information on
how to format these queries.

TARGET MODE QUERY
-----------------

The target mode query allows specification of an agent targeting string as would
be passed to the -t flag using MIG command line. This evaluates agents using the
targeting string as the command line would, returning matching agents.

A search query is a SQL WHERE condition. It can filter on any field present in
the MIG Agents table.
	     Column      |           Type
	-----------------+-------------------------
	 id              | numeric
	 name            | character varying(2048)

	 pid             | integer

	 heartbeattime   | timestamp with time zone
	 status          | character varying(255)
	 environment     | json
	 tags            | json
