Known Issues 

Date Description and Workaround (if any) Found in Release Fixed in Release

While running Quality Check for log parser wizards: Import Existing Configuration and Manual Configuration, you might encounter improper results. Because currently on the Sub Configuration page, the fields Preprocessor Class Name supports only the Rule-Based Preprocessor option, and the File Format supports only the Bluecoat option. If you select other options from the list besides the specified options on the Sub Configuration page, you will find invalid results.

This issue will be fixed in an upcoming release.

The date format doesn't automatically pick the selected Timestamp column from the Map Log Fields in the Log parser when there are multiple date header columns such as Date or Timestamp in the parsed logs. As a workaround, make sure to manually update the correct date format. 

NOTE: The Log Parser automatically picks the available date format when there are no multiple date header columns.

Cloud Connector throws ldapusers cache error after upgrading from 3.9.2 to 5.3.0 and above versions. As a workaround:

  1. Delete the ldapusers cache from the Cloud Connector installed directory (leveldb) and restart the Cloud Connector.
  2. Use the following curl command to push respective properties to YML with the mentioned payload when switching between rocksdb and leveldb:

Switching to leveldb

  "logProcessor":{ "unmatchedtracker.keyValueStoreType":"LEVELDB",
  "ipUserMapperStore.cache.type":"LEVELDB"   },
  "integration": {
    "smtp": {},
    "siem": {},
    "panorama": {},
    "custom_attributes": {},
    "ip_user_mapping": {},
    "syslog": {}

Switching to rocksdb

  "ipUserMapperStore.cache.type":"ROCKSDB"   },
  "integration": {
    "smtp": {},
    "siem": {},
    "panorama": {},
    "custom_attributes": {},
    "ip_user_mapping": {},
    "syslog": {}

NOTE: Before you switch between DBs, delete only the respective caches throwing exceptions after the Cloud Connector is started.
