This chapter includes information about:
The SNMP agent provides status information on various components in the uOne environment. You can view this information in real time using standard SNMP monitoring stations. Refer to "Supported MIBs" and "SNMP Trap IDs" for more information about SNMP support for uOne.
You perform the following tasks to ensure that uOne is functioning properly:
For the uOne system to run smoothly and be completely functional, all those server agents must be up and running at all times. A crucial part of your job is to ensure that the following uOne server agents are up on the system:
To view server agent status:
Step 1 At the command line, type: umcli -s get system status
A screen similar to the one shown in Figure 2-1 displays.
The ACB is a set of services used by agents for communications and other services. You should monitor the status of the ACB and agents to ensure that they are functioning properly
Step 1 At the command line, type: umcli.
Step 2 At the umcli prompt, type: watch acb globals.
A screen similar to the one shown inFigure 2-2 displays.
It is important to monitor H323 resources to ensure communications between the IP network and the CMA are functioning properly.
Step 1 At the command line, type: umcli.
Step 2 At the umcli prompt, type: watch h323 states.
A screen similar to the one shown in displays.
To ensure that subscribers are notified when they receive new messages in their mailboxes, it is a good idea to monitor whether MWI and paging notification requests are succeeding or failing.
Step 1 At the command line, type: umcli.
Step 2 At the umcli prompt, type: watch notify.
A screen similar to the one shown in Figure 2-4 displays.
To ensure that subscribers their Short Message Service notification when they receive new messages in their mailboxes, it is a good idea to monitor whether SMS notification requests are succeeding or failing.
Step 1 At the command line, type: umcli.
Step 2 At the umcli prompt, type: watch sms.
A screen similar to the one shown in Figure 2-4 displays.
To ensure that the FaxPrint application is successfully sending subscribers' faxes to a fax machine to be printed, it is a good idea to monitor whether FaxPrint activity.
Step 1 At the command line, type: umcli.
Step 2 At the umcli prompt, type: watch faxprint.
A screen similar to the one shown in Figure 2-4 displays.
To ensure optimal system performance, you should monitor the following resources on the GateServer:
Table 2-1 provides threshold recommendations for each of these resources on the GateServer, as well as the tools available for monitoring their performance.
| Resource | Monitoring Tool | Threshold |
|---|---|---|
File systems | df command (df -k) | No more than 80% capacity for these file systems: /home2, /tmp, /var, and /var/tmp. No more than 90% capacity for all remaining file systems. |
CPU | sar command (sar -u 5 2) | No less than 25% idle time. |
Memory | Use one of the following commands: (1) sar command (sar -r 5 2) Use this formula to calculate the percentage of memory used: Execute the dmesg command and look in the output for the total RAM bytes. | No more than 75% used. |
H323 ports | Access the umcli tool and issue this command: watch h323 states. Count the number of idle calls. | At least 2 voice ports should be idle |
Network bandwidth usage | netstat command (netstat -i) Use this formula to calculate the collision rate: ( coll / opkts ) * 100 | Refer to your LAN switch documentation. |
