NAME

xymonfetch - fetch client data from passive clients

SYNOPSIS

xymonfetch [--server=XYMON.SERVER.IP] [options]

DESCRIPTION

This utility is used to collect data from Xymon clients.

Normally, Xymon clients will themselves take care of sending all of their data directly to the Xymon server. In that case, you do not need this utility at all. However, in some network setups clients may be prohibited from establishing a connection to an external server such as the Xymon server, due to firewall policies. In such a setup you can configure the client to store all of the client data locally by enabling the msgcache(8) utility on the client, and using xymonfetch on the Xymon server to collect data from the clients.

xymonfetch will only collect data from clients that have the pulldata tag listed in the hosts.cfg(5) file. The IP-address listed in the hosts.cfg file must be correct, since this is the IP-address where xymonfetch will attempt to contact the client. If the msgcache daemon is running on a non-standard IP-address or portnumber, you can specify the portnumber as in pulldata=192.168.1.2:8084 for contacting the msgcache daemon using IP 192.168.1.2 port 8084. If the IP-address is omitted, the default IP in the hosts.cfg file is used. If the port number is omitted, the portnumber from the XYMONDPORT setting in xymonserver.cfg(5) is used (normally, this is port 1984).

OPTIONS

--server=XYMON.SERVER.IP: Defines the IP address of the Xymon server where the collected client messages are forwarded to. By default, messages are sent to the loopback address 127.0.0.1, i.e. to a Xymon server running on the same host as xymonfetch.
--interval=N: Sets the interval (in seconds) between polls of a client. Default: 60 seconds.
--id=N: Used when you have a setup with multiple Xymon servers. In that case, you must run xymonfetch on each of the Xymon servers, with xymonfetch instance using a different value of N. This allows several Xymon servers to pick up data from the clients running msgcache, and msgcache can distinguish between which messages have already been forwarded to which server.
N is a number in the range 1-31.
--log-interval=N: Limit how often xymonfetch will log problems with fetching data from a host, in seconds. Default: 900 seconds (15 minutes). This is to prevent a host that is down or where msgcache has not been started from flooding the xymonfetch logs. Note that this is ignored when debugging is enabled.
--debug: Enable debugging output.
