Extended event logging
InfoScale provides an option to enable extended event logging. When this option is enabled, InfoScale components provide EO-compliant messages in the corresponding log files, which adhere to the standard security requirements.
In case of interactive deployment, the InfoScale common product installer (CPI) prompts you to enable EO-compliant logging.
If you do not enable the option during InfoScale deployment, CPI provides the eocompliantlogging option, which you can use later as follows:
To enable EO-compliant logging, run:
# /opt/VRTS/install/installer -eocompliantlogging on
To disable EO-compliant logging, run:
# /opt/VRTS/install/installer -eocompliantlogging off
For example, when the eo_logging_tunable parameter is enabled using the vxtunefs command, the following InfoScale components log specific events or details:
VxFS logs events related to WORM (write once read many) and permission-denied events.
File Replicator (VFR) includes IP addresses of the systems involved in its events.
As part of InfoScale command logging, the following information is logged:
All the commands that are executed, along with any arguments that may have been used
Errors, if any, that occur when a command is executed
The log format comprises the following space-separated elements listed sequentially:
Timestamp in the YYYY-MM-DDTHH:MM:SS.mmm+hhmm format
Hostname in the fully qualified domain name (FQDN) format
Log file name
Command name
Sample InfoScale command logs format:
<YYYY-MM-DDTHH:MM:SS.mmm+hhmm> <FQDN_hostname> /opt/VRTS/bin/fsadm -o softworm /mnt2 <YYYY-MM-DDTHH:MM:SS.mmm+hhmm> <FQDN_hostname> /log by Ux:vxfs fsadm
