Redline Radios showing constant rebot

We are monitoring the Reline an50 radios, and have an issue with the system showing constant rebooting, even though the last system reboot shows 247 days of uptime.

is there a buffer limit on the the poller that will not allow data over a certian value then shows as a reboot?

Anybody that could assist would be appreciated.

  • Hi,

    The steps to troubleshoot this would be to first figure out what is the value stored in the database for the LastBoot field and what returns the device when Orion polls it. Once done this, we will know if the problem is due to Orion or the device.

    The below SQL query should give you the list of the devices and their respective Last Reboot datetime.

    SELECT Caption, LastBoot FROM Nodes

    If the value is mangled or malformed or show a date in the future (never seen that thought :), you should setup a wireshark trace or run a MIB walk to figure out what is returning the device.

    This value is polled from the following OID: 1.3.6.1.2.1.1.3 - sysUpTime

    Description: The time (in hundredths of a second) since the network management porting of the system was last re-initialized.

    HTH,

  • The sysUpTimeInstance (OID .1.3.6.1.2.1.1.3.0) as defined in the MIB (RFC1213-MIB) is a 32-bit unsigned integer, which will rollover at 248.5 days back to 0.

    I recommend replacing the object used (sysUpTimeInstance) with hrSystemUptime from HOST-RESOURCES-MIB (OID .1.3.6.1.2.1.25.1.1.0).

    This will not fix the rollover issue (needs logic around when to ignore the counter), but WILL give accurate SYSTEM uptime. I am not sure why you would care about SNMP client uptime.

       hrSystemUptime OBJECT-TYPE
           SYNTAX TimeTicks
           ACCESS read-only
           STATUS mandatory
           DESCRIPTION
                  "The amount of time since this host was last
                  initialized.  Note that this is different from
                  sysUpTime in MIB-II [3] because sysUpTime is the
                  uptime of the network management portion of the
                  system."
