Manage monitored guests logs
Description
A service can be defined in order to monitor the guests log files to look for key removal messages (based on interval defined on the dongle) and/or informational, warning and error messages. It also monitors in parallel dongle removal (immediate mode).
The service works with a list of log files to be monitored.
The log file name must be defined with full path within the configuration file.
Rotating log files are supported only with CHARON-AXP and CHARON-VAX V4.7 minimum and Linux Toolkit 42 minimum
Management
This option offers the possibility to edit the log file list, start/stop monitoring for a guest, view the guest log file, view the monitoring log file, install or update log monitoring service for Linux servers without "systemd
" feature (Red Hat 6) or to manage "systemd
" services for Linux servers with "systemd
" (Red Hat 7 and Fedora) and to start/restart the aksusb log monitoring.
Example1 - Red Hat 6:
Example2 - Red Hat 7:
Notes:
- The list of monitorted log files is automatically filled with the log files found in the configuration files for guests defined with the Service management (Start, Stop, Manage automatic boot & shutdown) menu option when selecting the "Update log files list" option 1.
- The install/update service option will just restart the log monitoring service and not the guest.
- The aksusbd log monitoring will look into the "
/var/log/messages
" log file (Red Hat 6) or will check thejournalctl
(Red Hat 7 and Fedora) and will send an alert on dongle removal and dongle detected quite immediately - The guest log monitoring:
- will send alerts when information, warning and error messages will be detected depending on the alert level defined at Alerts management - Select guests log alert level. Note alerts will be send in a bulk email message by default: one alert every 1 minute based on crontab entry settings for '
/opt/charon/utils/charon_logevent
' (see Manage recursive jobs: license expiration check, log events (cron)) - It will also send alerts on guest start and stop
- Dongle removal and detection alert messages will be sent based on license check interval defined with the license (default is 1 hour).
- Each time a license is detected in the guest log file, an expiration check will occur and will send alerts if necessary
- will send alerts when information, warning and error messages will be detected depending on the alert level defined at Alerts management - Select guests log alert level. Note alerts will be send in a bulk email message by default: one alert every 1 minute based on crontab entry settings for '
- If you remove a guest from the "Service management - Update guests list" option, the log monitoring service will be removed from the list
- In case you're using regular (main) and backup license dongles, you will receive a "License dongle found" alert on dongle switch.
If the alert tells you the license detected is a "Runtime limited license", you'll have to replace your regular dongle as soon as possible. - If you have more than one virtual machine running on the same server, do not use the same log file name more than once even if the log folders are different
- If you change the folder of an existing virtual machine, you'll have to update the service manually (Red Hat Enterprise Linux 7+ and Fedora)
