@ccie09: For multiple hosts it would require a new “source” entry for each host in symux.conf. You can specify different datadirs in each source entry. This would probably also require tweaking of the .layout files to bring in these different datadirs if you are using symon as well.

For the symux system accepting data from other hosts you need to change the mux line in symux.conf to an external interface( not localhost ). After you do that you would also have to configure the source line for the host you are running symux on via it’s external address because symux would no longer be accepting connections on the localhost device. Or you could have 2 mux entries and point the source entry for the machine that symux is to localhost. Whichever method your environment requires.

Hi,
in a scenario where i am monitoring more than 1 machine with symon installed on all of them, what datadir will i specify for the other monitor statements?

Also will the system running symux have a mux statement pointing to localhost or its ipaddress?

ok thanks im almost there. lol

my last problem is viewing the graphs with syweb
i.e.
“Congratulations! You should now be seeing graphs for collected Symon data by browsing to http://localhost/syweb. If you wish to modify the reports look at the .layout files in the layout_dir”

My questions are how do i browse to the files? do i do this form a web browser of another system or from the same system i have installed symon ? i have my rrd files located in /www/symon/localhost and the ip address of the machine is 10.1010.10. how do i browse to view th files?

The c_smrrds.sh script will generate the RRD’s for you. You need not change anything in the script. The script uses the configuration in symux.conf to determine which devices it will generate RRD’s for and where the RRD’s will be placed(the datadir directive).

hi, thanks for this, very helpful.

i got stuck at this point.

“Now that we have Symux configured we can use the provided /usr/local/share/symon/c_smrrds.sh (OpenBSD) script to generate the RRD files for the devices & processes we configured in Symux. Without generating the RRDs no data will be collected and starting the services will fail.”

how do i generate the rrd files? what do i have to modify on the script for this to occur?
thanks

I’m not quite sure what pfmux is and Google is coming up blank. You probably want to modify the pf.layout file that came with syweb. Using my provided configuration files you’ll notice I’m already collecting data for the pf interface.

Chances are you don’t have the same network interfaces that the developer does. Change the names of the RRD files in that file to reflect your interface RRD files and then replace all instances of xl0 and dc0 with your respective internal/external device names.

You should then be able to use the dropdown in the syweb interface to change from ‘default’ to ‘pf’.

nice post, thanks.

How to use symon / symux / syweb to collected detailed pf stats? I’m looking for a sample config for the various pf stats given in the pfmux manpage.

thanks
