Unexpected value in point

If a PI point is receiving an unexpected value, enable logging of debug output by setting the point’s location5 attribute to 3. The interface will log detailed information about the value that it received from the SNMP device. The following is an example of debug output from the log:

25-Oct-13 13:23:00
The interface- 1> pt (localhost_sysUptime_abs), rx data type: not explicitly checked for
25-Oct-13 13:23:00
The interface- 1> val.integer is 1598036
25-Oct-13 13:23:00
The interface- 1> pt (localhost_sysUptime_abs), t=1061583780.03 drval=0.185 ival=0 istat=0 returned to UniInt

This indicates that the interface:

• Received a value of 1598036 from the SNMP device.

• Sent a value of 0.185 to the PI Data Archive. (The conversion attribute of the point is 0.00000011574, which is 0.185 divided by 1598036.)

Changes to the location5 attribute might require up to two minutes to take effect. If you have changed a large number of point attributes, consider restarting the interface to enable it to detect all changes during startup. After resolving the problem, be sure to set location5 back to 0 to avoid bloating the log.
