The following issues have been identified to exist within Opsview Monitor 5.2:
Sometimes the upgrade process can appear to hang with the following message:
[ ok ] Restarting web server: apache2 ... waiting . Reloading Opsview Watchdog
This will resolve itself if you wait long enough (typically around 10 minutes), but can also be fixed by opening a second session onto the server and running the following command as the "nagios" or "root" user.
pkill -f starman
The upgrade process should then continue within 30 seconds.
There is a known issue with Jasper Reporting for users who are using Chrome and have upgraded from Windows 8 to Windows 10. A workaround for this is to use an alternative supported browser such as IE11 or Firefox.
RPM platforms have been found to hang on upgrade due to an issue with watchdog and the new timeseries packages. In order to resolve this, the upgrade steps in section Upgrading CentOS or RHEL systems to 5.2.x should be followed
There is a known issue for early 5.2.0 adopters where the following graphing errors can be seen in /var/log/opsview/opsviewd.log:
Timeseries ERROR: Unexpected EOF while reading response header at /opt/opsview/perl/lib/perl5/Opsview/Timeseries/Client.pm line 163.
This has been fixed in version 184.108.40.206701003 of the opsview-perl package, available in the repositories. Please ensure you have the latest versions of both opsview_perl and opsview_watchdog packages. After updating, the 'opsview-timeseries' daemon will need to be restarted. As the nagios user, run:
$ opsview_watchdog opsview-timeseries restart
In Graph Center using IE 11 and Edge, when >20 metrics are being used, some graph REST API calls will fail and show an "Error with network call" message, including a "Bad Gateway" error in a popup window.
This has been investigated and has been fixed in Opsview Monitor 5.3. It appears there is an issue in communication between IE, the Apache proxy and Catalyst. If you are experiencing this issue we recommend uprading to Opsview Monitor 5.3 or using the latest version of Firefox or Chrome.
Known Issue for installation on Ubuntu 16.04 please run these 2 additional commands after installation to fix a dependency issue.
