Chapter 7 - Service Statistics


Figure 7-1. Service Statistics Screen

SS - Server service, which provides communication among processes on the server.

ST - StreetTalk service, which manages naming in a network.

VS - Security service, which manages network security.

SNM, NM, and VCS - Network and systems management services.

Msgsin + Msgsout + Locin + Locout = Total

Note: The last five fields of information on the screen may not appear for some servers. In this case, the product revision on those servers does not support the statistics.

If the other server is on the same physical LAN as the workstations that will use it, move the service with the highest message traffic percentage. With this method, you off-load the current server without introducing any routing overhead.
If the other server is on a backbone LAN, you should move several infrequently used services. This strategy allows you to maintain maximum performance of your heavily used service. In addition, you replace the service load of the moved services with a routing load that is usually smaller.

The server is rebooted.
Services are restarted from the Operator Menu of the server console.
The service is started through OPERATE or MSERVICE.



Time Up

Factors That Influence Service Memory Use

The number of users of the service. As the number of users of a service increases, the amount of memory that the service uses tends to increase as well. Use the LOOK at service users function of MSERVICE to monitor the number of service users.
For the StreetTalk and Security services, the number of groups and users maintained on the server.

StreetTalk service
Security service
Intelligent Messaging mail service
Print service
SMTP service
STDA service
AFP service
Asynchronous Terminal Emulation service

Modify the size of cache space. This frees up memory for services to run in. See Chapter 15 for information on modifying the cache space.
Move services to servers that have sufficient memory capacity.
Stop unused or lightly used services.
Shut down and restart server software if swapping average remains above .01 for a long period of time.
Move large groups to other servers that have sufficient memory capacity or split up large groups into smaller groups and distribute them among several servers.
Reduce the number of service users as long as alternative services that can handle additional users are available.
