Symptom

• As for many other softwares, N4V and its components use some files to log or to work. Those files may grow over time and it may be necessary to delete them.

Environment

• Windows Server
• Need4Viz : all versions

Resolution

The following files can be deleted manually or automatically (through a custom script you can create) :

• \Need4Viz\logs\n4v_xxx_out__timestamp.log (rotate logs system generates one file a day)
• \Need4Viz\logs\n4v_xxx_err__timestamp.log (rotate logs system generates one file a day)

The working directory of N4V is used each time a chart is rendered to be printed. It can be emptied regularly :

• \Need4Viz\nodejs\node_modules\custom_element\ce_works\*

If MongoDB is used, you can also delette regularly the following log file (you can delete the file even if mongodb is running, a new log file will be recreate automatically when the service is restarted) :

• \MongoDB\Server\4.2\log\mongod.log
