FortiAnalyzer
FortiAnalyzer can receive logs and Windows host events directly from endpoints connected to EMS, and you can use FortiAnalyzer to analyze the logs and run reports.

Description

 

This article describes various ways to investigate and troubleshoot for FortiAnalyzer event handler-related issues.

 

Scope

 

FortiAnalyzer v7.4.0, v7.2.2 & above.

 

Solution

 

Note: In this article, 'Action=login' FortiGate event logs will be used to trigger the FortiAnalyzer event.

 

  1. Verify that the logs are received and visible under FortiAnalyzer -> Log View.

Once FortiAnalyzer has received the logs, the handler will trigger the event based on the handler rule and threshold settings:

  1. Verify fazalertd and sqllogd daemon are still running by running the following command:

 

faz# diag test app sqllogd 1

faz# diag test app fazalertd 1 -> fazalertd introduced starting from v7.2.2 & above.

 

  1. Verify whether the logs have hit the handler rule:

 

faz# diagnose test app sqllogd 200 conf adom=<adom-name> handler=<handler-name>

 

Example output:

 

faz# diagnose test app sqllogd 200 conf adom=test-adom handler="test-handler"

* Enabled rules in Adom test-adom [205] is 400:
----------------------------------------
Handler Name : test-handler/1780784373
Rule Name : test-rule/2608794398
Handler Type : Basic
Data Src Type : memory
Selector Name : test-selector
Log chk/hit : 4/2
<----- Verify whether the hit count increases after receiving the log.
Instance/AP/Sum: 1/1/1
Filterkey : 3869101813645295628

 

  1. Perform live debugging and verify whether the logs are triggering any event:

 

To enable live debugging:

 

faz# diagnose test app fazalertd 200 debug -> ensure it shows 'debug is on', else run the command again.

faz# diagnose debug enable

 

Replicate the event (e.g: Login from FortiGate). Verify and analyze the debug output.

 

To disable live debugging:

 

faz# diag test app fazalertd 200 debug

faz# diag debug disable

 

Sample output (when the event is triggered based on the log):

  1. Try restarting the sqllogd & fazalertd daemon, and verify the results again:

faz# diagnose test app sqllogd 99

faz# diagnose test app fazalertd 99

 

  1. If the commands above do not help, try the following commands to force restart the fazalertd daemon and verify the results again.
    Note: This will reset all correlated event handler data such as threshold window time.

 

faz# diagnose test app sqllogd 200 debug rocksdb reset fazalertd

Warning: This will reset fazalertd rocksdb and restart fazalertd,
execute the command again in one minute to reset fazalertd rocksdb.

faz#

faz# diagnose test app sqllogd 200 debug rocksdb reset fazalertd

The fazalertd rocksdb was reset

 

  1. Troubleshooting Event Generation Failure.

 

Send the corresponding information in the ticket:

 

  • Config of FortiAnalyzer.
  • Raw log of FortiAnalyzer.
  • exe tac report

 

diagnose test connection mailserver <mailserver> <source SMTP address> <destination SMTP address>

 

The following commands on the FortiAnalyzer will provide more information regarding the SMTP client application.

For FortiManager / FortiAnalyzer 7.6 or above, perform a flow capture:

 

diagnose test application fazmaild ?

<Integer> Debug level (08).

diagnose debug application fazmaild 8

diagnose debug timestamp enable

diagnose debug enable

 

diagnose debug disable <- To stop it.

diagnose debug reset

 

In the FortiAnalyzer, enter the following commands while running a 'diag log test' action in the FortiGate CLI:

 

diagnose test application sqllogd 200

diagnose test application sqllogd 200 status

diagnose test application sqllogd 200 config

diagnose debug application sqllogd 8

diagnose debug enable

diagnose debug application fazmaild 255

diagnose debug disable

diagnose debug reset
