uCosminexus Application Server, Operation, Monitoring, and Linkage Guide
You need to maintain stable operating conditions by checking that the status of a logical server and the statistics of a running system are appropriate. You also need to determine whether tuning is required based on the system performance output in the statistics.
This subsection gives an overview of operations that monitor the system operations. The following table describes the monitoring of system operation:
Table 2-3 Monitoring system operations
Operation contents | Measure | Operation overview | Reference manual | Section |
---|---|---|---|---|
Monitoring the status of service units | Smart Composer functionality commands (cmx_list_status command) | You can check the status of service units in the Web system and can monitor that the system is running normally. | This manual | 2.5.2(1) |
Monitoring the status of a logical server | Management command (mngsvrutil) | You can check the status of hosts and servers that configure the system and monitor whether the system is running normally. Based on this information, you can start, stop, and restart the system, as required. You can confirm the status of a logical server in the following units:
|
2.5.2(2) | |
Monitoring system operations | Statistics collection function#1 #2 | You can monitor the operation status of J2EE servers, batch servers, or SFO servers, and can display the status in a statistics file. By monitoring the system performance, you can find the locations in the system where errors occur and this can help for performance tuning. |
3.2 | |
Management command (mngsvrutil) | You can monitor the operation status of J2EE servers, batch servers, or SFO servers, and can display the status in a CSV format file. By monitoring the system performance, you can find the locations in the system where errors occur and this can help for performance tuning. |
8.2 | ||
Function for monitoring resource depletion#1 #3 | By monitoring the transition of usage rate and the number of resources, the system can output a message when the usage rate or the number of used resources exceeds the threshold value. The system can periodically output the transition of usage rate and number of used resources as the resource depletion monitoring information. When the threshold value is exceeded, you can prevent the occurrence of an error by analyzing the cause based on the output resource depletion monitoring information and take an appropriate action. Further, the resource depletion monitoring information is useful in analyzing the cause of an error. | 4.2 | ||
Management command (mngsvrutil) | You can check the statistics for CTM#4 that exist in the management domain for the following units:
|
10.2 | ||
Checking the transaction information | Server management commands (cjlisttrn) | You check information, such as the transaction status on running J2EE servers or the existence of a pending transaction on the stopped J2EE servers. | Common Container Functionality Guide | 3.15.9 |
