Components Used
This document is not restricted to specific software and hardware versions.
The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.
Problem
Cisco StarOS platforms is designed to transfer only the configured amount of Bulk Statistics data (bulkstats) to repositories such as Cisco PRIME server, Cisco Web Element Manager server (WEM) and Cisco Mobility Unified Reporting and Analytics server (MURAL). If the configured bulkstats file size limit is smaller than the actual bulkstats file then the StarOS skips some of the schema that is sent to the northbound repository server. This causes loss of bulkstat data storage and prevents the repository servers from displaying all the Key Performance Indicator (KPI) for the StarOS Node.
Symptoms
Cisco management servers may not able to display all the bulkstats KPI data from StarOS nodes. In such a case, the Simple Network Management Protocol (SNMP) trap is displayed.
SNMP Trap:
Fri Mar 04 22:15:01 2016 Internal trap notification 1312 (StatFilesizeExceeded) Bulkstat filesize threshold limit 4915200 measured value 6142481
This issue arises from a small bulkstats file size limit configuration as shown in this example:
******** show bulkstats *******
Friday March 04 22:45:24 UTC 2016
Bulk Statistics Server Configuration:
Server State: Enabled
File Limit: 4800 KB
Sample Interval: 15 minutes (0D 0H 15M)
Transfer Interval: 15 minutes (0D 0H 15M)
Receiver Mode: Secondary-on-failure
Historical Data Collection: Disabled
Resolution
To resolve this issue configure the file size limit according to the number of schemas you have configured in the StarOS platform. Monitor SNMP trap and make sure that bulkstats file size limit is not exceeded.
Note that the SNMP trap prints value is Bytes. However, the configuration takes values in KB (Kilo Bytes).
In the example, the configuration shows file size limit of set of 6000.
