    Background Ping

    Background Ping allows you to ping all devices in the Live network and will send an event to the Event Browser if a device becomes unreachable. Enabling Background Ping and setting its parameters are done at the Main Menu during installation. Or it can be done at a later time by running command /u/wandl/bin/changeconfig.sh as wandl. The following parameters are set or edited directly in the file /u/wandl/db/config/diag.xml.The client must be restarted for new settings to take effect.

    • <interval> is the amount of time in seconds between the next Background Ping execution. To disable Background Ping, set the interval <= 10.
    • <fpingpath> is the path of the fping tool which is normally found at /u/wandl/thirdparty/fping/fping
    • <nretries> is the number of retries Background Ping will attempt if ping fails.
    • <retry_interval> is the amount of time in seconds between the next ping retry attempt.
    • <try_snmp> use 0 (disable) or 1 (enable). If enabled, when all ping attempts fail, the last retry for connectivity testing will be done by SNMP query for the sysName or sysDescr of the device
    • <try_cli> use 0 (disable) or 1 (enable). If enabled, when all ping attempts fail, the last retry for connectivity testing will be done by running a CLI command on the device.
    • <skip> will exclude certain devices from being pinged. Use the hostname of the device or a range of IP addresses. Example syntax to define an IP range is 192.168.1.[10-200]. This tag is added by directly modifying the diag.xml file.
    • <threadcount> will set the number of threads The default value is 10. This tag is added by directly modifying the diag.xml file.

      Sample diag.xml configuration:

      <DevicePing>
      <interval>60</interval>
      <fpingpath>/u/wandl/thirdparty/fping/fping</fpingpath>
      <nretries>0</netries>
      <try_snmp>1</try_snmp>
      <try_cli>0</try_cli>
      <skip>R1</skip>
      <skip>R2</skip>
      </DevicePing>
