ganeti-mond - Ganeti monitoring daemon
ganeti-mond [-f] [-d] [-p PORT] [-b ADDRESS] [--no-user-checks]
ganeti-mond is the daemon providing the Ganeti monitoring functionality. It is responsible for running the data collectors and to provide the collected information through a HTTP interface.
For testing purposes, you can give the -f option and the program won't detach from the running terminal.
Debug-level message can be activated by giving the -d option.
The ganeti-mond daemon listens to port 1815 TCP, on all interfaces, by default. The port can be overridden by an entry the services database by passing the -p option. The -b option can be used to specify the address to bind to (defaults to 0.0.0.0). The daemon will refuse to start if the user and group do not match the one defined at build time; this behaviour can be overridden by the --no-user-checks option.
The queries to the monitoring agent will be HTTP GET requests on port 1815. The answer will be encoded in JSON format and will depend on the specific accessed resource.
If a request is sent to a non-existing resource, a 404 error will be returned by the HTTP server.
/The root resource. It will return the list of the supported protocol version numbers.
/1/list/collectorsReturns a list of tuples (kind, category, name) showing all the collectors available in the system.
/1/report/allA list of the reports of all the data collectors.
Status reporting collectors will provide their output in non-verbose format. The verbose format can be requested by adding the parameter verbose=1 to the request.
/1/report/[category]/[collector_name]Returns the report of the collector [collector_name] that belongs to the specified [category].
If a collector does not belong to any category, collector will be used as the value for [category].
Status reporting collectors will provide their output in non-verbose format. The verbose format can be requested by adding the parameter verbose=1 to the request.
Further information can be found in the Ganeti Monitoring Agent design document.
