[opennms-discuss] Newbie questions

[Jesus M. S. Jr. <jes...@mi...>]

I was figuring out which one I should use: nagios, zabbix, or opennms.
Given that I am also a Java developer, I decided to give opennms a try 
... in the hope that I can understand and contribute some time in the 
future.

First off, after following all the installation instructions ( 
installing on FC2 ), I thought I have to configure  
discovery-configuration.xml.
But since I was curious what the web interface would look like, I 
decided to startup the Tomcat ( currently using 4.1.30 that I downloaded 
from Jakarta Apache ) and install the webapp. Symlinked from webapps 
directory, Added the users in tomcat-users.xml, and viola!
I was surprised that opennms already discovered the nodes and services!

Now to some questions:

1) In the index.jsp in opennms/ URI, the Categories defined, have always 
shown "Outages: Calculating..." and "Availability: Calculating..." for 
whole day already. What do I need to do so that it actually shows the 
figures ?

2) On my test environment, I have a Sun E220R and 2 x Netra T1s, all 
running Solaris8.  When I select to show the performance results, the 
only available performance results for the Sun 220R are traffic-related 
( 3 graphs: In/Out Traffic Utilization, Bits In/Out, and Errors In/Out 
). But if I select the performance resutls for the two Netra T1s, I get 
a few more graphs such as CPU Time, Paging, Swapping, Disk Transfer 
Rate, Discards In/Out, Packet Statistics. Any clue as to why that would 
be ? I suppose that the Sun E220R was not making these data available 
via SNMP, but not sure which OID to verify that it is the case.

3) Also, on FC2 where OpenNMS is running, snmpd is also running. 
However, I dont have the option to select "Performance Results" for this 
node, even though it opennms knows that SNMP is a service running on 
that node. Having said that, snmpd was not running initially when 
opennms was started, but I started snmpd and then forced a rescan of the 
node, which generated an event that "snmp has been discovered", but no 
"performance results" / "snmp performance" option. I can see "Response 
Time" though.

I have more questions, but I'll reserve them later after reading more 
documentation.

Thanks and good work!
