newbie questions

[harryl]

Hi All,

I just installed Cacti, and was trying to add a device in the same network. however, the device I added seem to have a SNMP error on the top left handside. Does the device I added need to install net-snmp, too?

And one thing is that, there are some images can not be shown when I view the graph.

Any ideas?

Thanks in advance

Hi

Yes, it's the best way to graph a remote device.

And one thing is that, there are some images can not be shown when I view the graph.

Are you sure the poller is running ?

Thanks for the reply.

I have this crontab job running for pooling. However, I have never see the graph changed.

*/5 * * * * root /opt/lampp/bin/php /local/htdocs/cacti/poller.php > /dev/null 2>&1

So, do I need to do any sort of configuration on the server net-snmp and the client net-snmp? I installed net-snmp and it seems like it still getting this snmp error on machine infofmation.

Thanks

Please see http://docs.cacti.net/node/411 for basic SNMP stuff

Thank you so much!!
Finally got the poll and SNMP working.

However, I am running into another problem.
I tried to graph the ethernet traffic with I/O Bits with Total BandWidth. When I go to graph, the graph did not display. I revisit it after 30 min, it still displaying the picture display error sign. But I can see the graph fine when I click on the magnifier next to it.

Any ideas?

Thanks

Please verify rrdtool settings (Settings-> RRDTool Utility version) and verfify font names if you have specified any

The RRDTool Font Path is this: /usr/local/rrdtool-1.2.23/share/rrdtool/fonts/DejaVuSansMono-Roman.ttf

And the RRDTool version shown in settings is RRDTool 1.2.x

Everything is in default setting. wandering what goes wrong.

Please visit this graph at Graph Management. Switch to DEBUG mode and post a screenshot of the whole page.
