# SUM log file locations

##

SUM stores log files in the following locations:

User logs

  Windows directory: `C:\cpqsystem\sum\log`

  Linux directory: `/var/log/sum`

Debug logs

  Local Windows directory: `%LOCALAPPDATA%\sum`.

  Remote Windows directory: `Admin$\Temp\sum`.

  Linux directory: `/var/tmp/sum`

Local copy of SUM binaries when needed

  Windows directory: `%LOCALAPPDATA%\localsum`

  Linux directory: `/var/tmp/localsum`

  SUM makes a local copy of binaries and support files when SUM is launched from a network-mounted share or read-only location. This provides SUM uninterrupted access during updates.

Remote node files

  Windows directory: `Admin$\temp\sum`

  Linux directory: `/var/tmp/sum`

NOTE:

If you do not find logs in the locations listed on Linux systems, check the directory `/var/cpq/Component.log`.

SUM also creates audit logs in the operating system event logs as follows:

- Windows: Windows Event log

- Linux and VMware: sys logs

Audit logs track activities such as SUM logins and component installs.
