The Metering Log

The metering simulator writes transaction data for each service invocation that would be metered by webMethods Metering Agent to the metering log. You can use the metering log to view and analyze service metering data. The metering log is a comma-separated values file named metering.csv and is located at: Integration Server_directory\instances\instanceName\logs.

Note:
The metering log was introduced by PIE-85053 (IS_10.15_Core_Fix8). Prior to PIE-85053, the metering simulator wrote transaction information to the server log.

Following is a sample of a metering.csv log metered service for an Integration Server where the TxnTimer value in the license key is set to 3, meaning the transaction duration is 3 seconds (3000 ms):

timestamp,svcName,tenant,user,duration(ms),trans_count

2023-08-30 16:25:26 EDT,services:scheduled_service,,myUser,27000,9
2023-08-30 16:27:47 EDT,services:addAccount,,userA,127,1
2023-08-30 16:38:51 EDT,services:orderFlow,,userB,1000,1

CSV Field Name	Description
timestamp	Timestamp at which the metering simulator wrote the log entry to the metering log.
svcName	Name of the top-level service for which the metering simulator is generating metrics
tenant	The tenantID. If the tenant is null, such as in a self-hosted runtime, the metering simulator inserts a blank space in the tenant field.
user	Name of the user that initiated the transaction.
duration	Duration of the service, measured in millisecond
trans_count	Number of transactions counted for this single service invocation.

The value of the watt.server.statsLogRotateInterval server configuration parameter determines the frequency with which the metering log rotates. Integration Server names the rotated log metering yyyyMMdd_HHmmssSSSZ.csv.

Note:
The fields in the metering log are similar to what the metering simulator previously wrote to the server log with the following differences:
