Chapter 5 Cisco Unified Real-Time Monitoring Tool Tracing, PerfMon Counters, and Alerts
Description
This counter represents the number of times a script error occurred when the script
loaded into memory in Cisco Unified Communications Manager. A script can fail
to load due to memory issues or syntax errors.
Check the SIPNormalizationScriptError alarm for details. Check the script syntax
for errors, upload the corrected script as needed, and reset the trunk. This counter
increments every time a load error occurs. This counter provides a count from the
most recent trunk reset that was accompanied by a script configuration change. (A
device reset alone will not restart the count; the script configuration must also
change before the reset occurs.) If the counter continues to increment even after you
fix the script problem, examine the script again.
This counter indicates whether the script encountered a resource error.
Two kinds of resource errors exist: exceeding the value in the Memory Threshold
field and exceeding the value in the Lua Instruction Threshold field. (Both fields
display on the SIP Normalization Script Configuration window in Cisco Unified
Communications Manager Administration.) If either condition occurs, Cisco
Unified Communications Manager immediately closes the script and issues the
SIPNormalizationScriptError alarm.
If a resource error occurs while the script loads or initializes, the script is disabled.
If a resource error occurs during execution, the configured system resource error
recovery action is taken. (The setting of the System Resource Error Recovery
Action field on the SIP Normalization Script Configuration window in Cisco
Unified Communications Manager Administration defines this action.)
This counter specifies the amount of memory, in bytes, that the script consumes.
This counter increases and decreases to match the amount of memory that the script
uses. This count gets cleared when the script closes (because a closed script does
not consume memory) and restarts when the script opens (gets enabled). A high
number in this counter indicates a resource problem. Check the
MemoryUsagePercentage counter and the SIPNormalizationResourceWarning
alarm, which occur when the resource consumption exceeds an internally set
threshold.
This counter specifies the percentage of the total amount of memory that the script
consumes.
The value in this counter is derived by dividing the value in the MemoryUsage
counter by the value in the Memory Threshold field (in the SIP Normalization Script
Configuration window) and multiplying the result by 100 to arrive at a percentage.
This counter increases and decreases in accordance with the MemoryUsage counter.
This count gets cleared when the script closes (because closed scripts do not
consume memory) and restarts when the script opens (gets enabled). When this
counter reaches the internally controlled resource threshold, the
SIPNormalizationResourceWarning alarm is issued.
