Endpoint performance - setting the cache_limit

Technote (FAQ)


Question

Inventory scans and Software Distributions to endpoints may exceed the method cache limit.

Cause

The default cache_limit is too small.
In the lcfd.log (at log_threshold=3), you will see errors like the following:

Answer

TMF version 4.3.1 provides the ability to change the default endpoint method cache size

(20MB) to a higher value to accommodate the added requirements of applications such as

Inventory and SWD when the cache may be out-of-date and need to be reloaded.

cache_limit=max_size
Specifies the maximum size of the method cache. After this
maximum size is reached, the least recently used methods are
deleted to make room for current methods.

This can be set at install time with the "-D cache_limit=<max_size>" argument to winstlcf
or set after the endpoint is installed using:

wep <ep_label> set_config cache_limit=<max_size>
