xymonfetch - fetch client data from passive clients
xymonfetch [--server=XYMON.SERVER.IP] [options]
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).
- --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.
