## Troubleshooting

### Log Files

If you are encountering any issues with NetAudit, please view system logs in /var/log/opsview/opsview.log.

### I've added a new host, but there isn't an SVN entry created

When a 'Apply Changes' occurs, Opsview Monitor will generate a list of all the hosts that have RANCID enabled. However, if the websvn repository doesn't show the host, check whether 'opsview-netaudit' service is running or not with opsview-monit:


### Host appears in WebSVN, but it is empty
The flow of data for NetAudit is:
  • rancid collection is invoked on NetAudit Collector every 4 hours via a cron job
  • a message with configuration data is sent to NetAudit master where opsview-netaudit service runs
  • opsview-netaudit will process message and run an "svn commit" to commit the changes to svn
If your host file is listed in WebSVN (NetAudit page) under 'rancid' repository but it is empty, it might be because the NetAudit Collector hasn't run yet since it runs every 4 hours. You can run NetAudit Collector manually by connecting NetAudit Collector and run the following command as 'opsview' user:

### Where are the rancid configuration files?
/opt/opsview/netauditcollector/var/
routers.conf is the main configuration file for collections.
/opt/opsview/netaudit/var/
definition.xml is the configuration file for NetAudit hosts being monitored and the notification emails.
### Has the router configuration reached SVN?
Look in /opt/opsview/netaudit/var/svn/ on NetAudit master. If the file here contains information, then this is what should be in subversion. You can run an "svn status" to check compared with the subversion repository. 
### SVN shows the file, but WebSVN shows a blank file
This could be due to enscript. In /opt/opsview/repository/include/config.php, make sure the following line is uncommented (e.g. doesn't have # at the beginning):
$config->useEnscript(); If websvn now shows the router configuration, then there is probably an issue with enscript software.
### Where are the latest files?
On the NetAudit master, in /opt/opsview/netaudit/var/svn/ will be all the latest versions of the RANCID router output files.
### Troubleshooting NetAudit tab test connection
This simulates running the code to test the NetAudit connection with credentials:

Change 'cisco' with your vendor type, and 'telnet' with your connection method. You can add "-A" option at the end if you are using RANCID "autoenable" feature.
### NetAudit is installed but NetAudit page and menus are not visible in Opsview Web UI
NetAudit postinstall script might not have been run properly. You can run it manually as below as root user:

### Error: `no matching cypher type found`
When testing a connection you may see this error:

This means the SSH protocol is unable to agree on a common cypher between the Collector and the network device (in this case `3des` is not available on the device).  To amend the cypher used you can edit `/opt/opsview/netaudit/var/cloginrc_local` on the Orchestrator with a line such as 

where `<hostname_in_opsview>` is the configured hostname (as seen in the error) and `<cypher>` is an available option on the network device.  You can list available cypher on the Collector by running `ssh -Q cipher`  to pick one that both sides can use.
This change is distributed to all Collectors when an `Apply Changes` is performed in the UI.
