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)
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
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
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
- 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
- Sets the interval (in seconds) between polls of a client. Default: 60
- 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.
- 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.
- Enable debugging output.
