EVM Server Logs
The EVM server log includes information about the following:
• Storage refreshes
• Job status changes
• EVM Command Line (EVMCL) and GUI update requests
• EVM host agent interaction
To prevent the EVM server log files from consuming too much disk space, EVM
automatically archives the existing log file and starts a new one. Archiving occurs
whenever the EVM server log file size reaches 10 megabytes or whenever the EVM
server is restarted.
Seven generations of EVM server log files are maintained. A file named evm1.txt is
the current log and evm7.txt is the oldest.
EVM Job Logs
Log files are kept for each EVM job. When a job runs for the first time, an EVM job
log file (such as job_name.txt) is created for this job and the individual operations that
comprise the job are recorded in the job log file. Detailed information about the job
state also is recorded in the job log file. Each time a job is executed, the current EVM
job log file for that job is archived and a new EVM job log file is created.
Seven generations of EVM job log files are maintained. The file-name format for an
EVM job log file uses the EVM job name and a sequential number. For example, an
EVM job log file named jobname_1.txt is the current log and jobname_7.txt is the
oldest.
EVM Switchboard Logs
The Switchboard process implements EVM functionality on each EVM host agent
computer. There is a Switchboard portion implemented on the host agents and another
Switchboard portion implemented on the Management Appliance (EVM server).
View the EVM Switchboard log files (sb.txt) on the EVM server in the Log Report
page. These logs contain primarily startup and initialization information about each
EVM host agent computer in the EVM network. This information is used to diagnose
host configuration, EVM host agent connectivity, and communication problems.
