Edit Watchdog Service Settings

Edit the Watchdog settings to change configuration values such as thresholds, trap settings, polling settings, notification address, and community strings.

Follow these steps:

1. Display the Watchdog Settings page:
   1. Select Administration from the NFA console menu.

      The Administration page opens.

   2. Select Health: Watchdog Settings from the Administration page menu.

      The Watchdog Settings page opens and displays the current settings.

2. Edit the Watchdog Service settings:

   Community String

   SNMP string that the Watchdog services use to verify the identity of components in a distributed deployment. The community string is used for gathering information from Harvesters (and from DSAs in a three-tier architecture deployment). Use the same community name throughout the CA Network Flow Analysis deployment:

   • Watchdog Settings page
   • SNMP service on each Windows server
   • snmpd.conf file on each Linux server

   Default: public

   CPU Threshold

   Threshold for CPU utilization. You are notified by email when the CPU threshold on a server is exceeded on any server and an SNMP trap notification is generated, provided that the address and string are set.

   Default: 80 percent CPU utilization

   Disk Threshold

   Threshold for disk utilization. If the disk threshold on a server is exceeded, you are notified by email and an SNMP trap notification is generated, provided that the address and string are set.

   Default: 80 percent disk utilization

   Email Address

   Destination email address to use for email notifications when thresholds are exceeded. To notify multiple recipients, separate the addresses with commas. The Email Address setting has no default value.

   Default: (none)

   Memory Threshold

   Threshold for memory utilization. You are notified by email when the memory threshold on a server is exceeded, provided that the address and string are set.

   Default: 80 percent memory utilization

   SNMP Retries

   Number of times the program attempts to poll an SNMP device. A high number of SNMP Retries can affect performance, depending on your network configuration.

   Default: 2

   SNMP Timeout

   Number of seconds before an SNMP poll times out.

   Default: 5

   System Check Interval

   Number of minutes between Watchdog system checks.

   Default: 60

   Trap Community String

   SNMP string to use for sending traps to a third-party trap receiver. Use one of the community names that the trap receiver is configured to accept.

   Default: public

   Trap Destination

   IP address of the server that receives SNMP traps from the Watchdog Services. The traps are generated when thresholds for CA Network Flow Analysis component performance are violated.

   Default: (none)
