FortiSIEM Configuring Monitoring

Configuring Monitoring

Once FortiSIEM discovers your devices, they will monitored continuously, and you can use the data collected to analyze the performance of your infrastructure. You can also configure FortiSIEM to send notifications when events that meet specific conditions occur in your infrastructure.

You can disable the collection of metrics for specific devices, disable devices for monitoring, and change the polling interval for metric collection.

Some devices need to be configured to send logs to FortiSIEM, as described in the topics under Configuring External Systems for Discovery, Monitoring and Log Collection. You can also configure FortiSIEM to monitor important ports, processes, and interfaces, and set up monitoring tests that use synthetic transaction to make sure that critical services are up and running.

Device Monitoring Settings

While FortiSIEM constantly monitors and reports on your IT infrastructure, there are several settings you can use to refine reporting on critical interfaces, important processes and ports, and disk utilization.

Adding Important Interfaces

Adding Important Processes

Adding Important Ports

Excluding Disks from Disk Capacity Utilization Monitoring

Adding Important Interfaces

This setting allows you to always get interface utilization reports on a set of important network interfaces across all device types.

Important Interface Setup after 4.8.1 Upgrade

The behavior of interface monitoring has dramatically changed since 4.8. So it is very important to follow these steps.

  1. Create a list of all Important interfaces
  2. Go to Admin > General Settings > Monitoring > Important Interfaces Click Enable. This will stop all interface monitoring.
  3. Click
  4. Select either Device View or Interface View.
  5. Select a device to view and select its interfaces, or select an interface.
  6. Click OK to add the selected interface to the list. The Critical and Monitor boxes would be automatically checked.
  7. Check the WAN box if applicable. If checked, the interface utilization events would have isWAN = “yes” attribute. You can use this to run a report for all WAN interfaces.
  8. Click Apply All. Now FortiSIEM will start monitoring only the selected interfaces in this tab will be monitored.
  9. If you want to disable this behavior and return to ALL interface monitoring (as in releases prior to 4.8), then click Disable.
Adding Important Processes

This setting allows you to always get process resource utilization reports and up/down alerts on a set of important processes across all device types.

Important Process Setup after 4.8.1 Upgrade

The behavior of process utilization monitoring has dramatically changed since 4.8. So it is very important to follow these steps.

  1. Create a list of all Important interfaces
  2. Go to Admin > General Settings > Monitoring > Important Processes Click Enable. This will stop all interface monitoring.
  3. Click
  4. Enter a Process Name and any Parameters, and then click OK.
  5. Click Apply All. Now FortiSIEM will start monitoring only the selected processes in this tab.
  6. If you want to disable this behavior and return to ALl interface monitoring, then click Disable.
Adding Important Ports

Always reporting the UP/DOWN status for every TCP/UDP port on every server can consume a significant amount of resources. FortiSIEM will report the UP/DOWN status only for the ports you add to the Important Ports list. Matching is exact based on port number and IP protocol.

  1. Go to Admin > General Settings > Monitoring.
  2. Under Important Ports, click Add.
  3. Enter the Port Number and select the Port Type.
  4. Click OK.
  5. Click Apply All.
Excluding Disks from Disk Capacity Utilization Monitoring

You can exclude disks from disk capacity utilization monitoring. Disk capacity utilization events will not be generated for devices matching the device name, access IP, and disk name that you provide. Incidents will not trigger for these events, and the disks will not show up in summary dashboards.

  1. Under Excluded Disks, click Add.
  2. Select a device to to view its disks, and then select the disk you want to exclude from monitoring.
  3. Click OK.
  4. Click Apply All.
Managing Monitoring of System and Application Metrics for Devices

When FortiSIEM discovers devices, it also discovers the system and application metics that can be monitored for each device, and displays these in the Monitor Change/Performance tab of the Setup Wizard. Here you can also disable the monitoring of specific metrics for devices, disable devices from being monitored, and change the polling interval for specific metrics. See Inspecting Event Pulling Methods for Devices for an explanation of the different status indicators for System Monitor and Application Monitor metrics.

  1. Go to Admin > Setup Wizard > Monitor Change/Performance.
  2. Click Refresh to make sure you have the latest list of devices.
  3. To disable monitoring for a device, clear the Enable option for it.
  4. To enable or disable monitoring of a specific metrics for a device, click on a device to select it, then click Edit and select System Monitoring or Application Monitoring to view the list of metrics associated with that monitor and device.
  5. To change the polling interval for a metric, in the More menu, select Set Intervals. Select the Monitor Type and Device, and then set the interval.
  6. When you are done making changes, click Apply.
Setting Up Synthetic Transaction Monitoring Tests

A Synthetic Transaction Monitoring (STM) test lets you test whether a service is up or down, and measure the response time. An STM test can range from something as simple as pinging a service, to something as complex as sending and receiving an email or a nested Web transaction. Setting up an STM test involves defining the type of monitor, associating the monitor definition to a device and testing it, and then deploying the STM test to a Supervisor or Collector. You can view the results of STM tests in the Synthetic Transaction Monitoring page, either by navigating to Summary Dashboard > Availability/Performance > Application Summary > Synthetic Transaction Monitoring, or to Admin > Setup Wizard > Synthetic Transaction Monitoring, and then clicking on Monitoring Status. You can also report on the results of STM tests in the reports Top Applications By Synthetic Transaction Response Time and Top Applications By Synthetic Transaction Response Time –

Detailed view. When an STM test fails, three system rules are triggered, and you can receive an email notification of that failure by creating a notification policy for these rules.

System Rule Description
Service Degraded – Slow

Response to STM

Detects that the response time of an end-user monitored service is greater than a defined threshold (average over 3 samples in 15 minutes is more than 5 seconds)
Service Down – No Response to STM Detects a service suddenly went down from the up state and is no longer responding to synthetic transaction monitoring probes.
Service Staying Down – No

Response to STM

Detects a service staying down, meaning that it went from up to down and did not come up, and is no longer responding to end user monitoring probes
  1. Go to Admin > Setup Wizard > Synthetic Transaction Monitoring.
  2. Click Add.
  3. Enter a Name and Description for the test.
  4. For Frequency, enter how often, in minutes, you want the test to run.
  5. Select the Protocol for your test.

See Protocol Settings for Synthetic Transaction Monitoring Tests for more information about the settings and test results for specific protocols.

  1. Click Save.

You now have to associate the STM test with a target host name, IP address, or IP range.

  1. Click Create and Test.
  2. For Monitoring Definition select one of the STM tests you have created.
  3. For Host Name or IP/Range, enter the information for your STM test target.
  4. For Port, click + and enter any ports to use when connecting to the target with this test.
  5. Click OK.

FortiSIEM will run the test and verify if it is successful. If it succeeds, it will be added to the list of tests with a yellow Star next to it, indicating that it has been added but is not yet running.

  1. Click Apply All to begin executing your tests at their set frequency.

The yellow Star will be removed from your test after it executes against the target the first time

 

Protocol Settings for Synthetic Transaction Monitoring Tests

This table describes the settings associated with the various protocols used for setting up Synthetic Transaction Monitoring tests.

Protocol Description Settings Notes
Ping Checks packet loss and round trip time Maximum Packet Loss PCT: tolerable packet loss

Maximum Average Round Trip Time: tolerable round trip time (seconds) from FortiSIEM to the destination and back

If either of these two thresholds are exceeded, then the test is considered as failed.

Adding a Synthetic Monitoring Test to a Business Service

You may want to add a Synthetic Transaction Monitoring (STM) test to a Business Service as part of the monitoring infrastructure for that service. However, in order to enable reporting on that STM, you need to add it to the business service as a device that FortiSIEM can then report on. This topic explains how to create a device for an STM test and add it to your business service report.

  1. Create your STM as described in Setting Up Synthetic Transaction Monitoring Tests.
  2. Note the IP address that your STM resolves to in Step 9 of the setup instructions.
  3. In the CMDB tab, select Devices, and then select a subcategory where you want to add the STM device.

You may want to create your own group where you manage your STM devices.

  1. In the summary pane for the device subcategory, click New.
  2. Complete all relevant information for the STM device, providing the IP address/range from Step 2 in the Access IP field of the Summary
  3. Click Save when you’re done entering device information for the STM.
  4. Follow the instructions in Creating a Report to add information about the STM device to a business service report, and then use the instructions in Adding Widgets to Dashboards to add it to your dashboard.
