Configure Logging
NCache gives you full control over cache monitoring so that you can log cache activity according to your requirements. In this section, you will learn how about a few basic logging parameters.
Important
In case you want to update any cache settings, please refer to the Update Cache Config section to follow the set of steps.
License Logging
LicenseLogging specifies whether this service will log license information for the server or not.
<add key="NCacheServer.LicenseLogging" value="false"/>
Windows Event Logging
Enables/Disables the logging of client connectivity events into Windows Logs. By default these events are disabled.
<add key="NCacheServer.LogClientEvents" value="false"/>
Specifies the level of events that are logged into Windows Logs. There are three levels of events:
- ERROR: Only errors will be logged
- WARNING: Errors and Warnings will be logged
- All: All events will be logged
<add key="NCacheServer.EventLogLevel" value="all"/>
Logging Sliding Expiration
The following four options allow a user to get information about data in a cache having sliding expiration. These counters help find and control the following tasks.
- How many items are present in the cache, being not accessed since a given interval or more?
- Log all those keys being not accessed since a given interval or more.
- Collect and Log the above-mentioned data from the cache after a given interval of time.
EnableCacheLastAccessCount enables or disables the logging of the DataLastAccessCount.
<add key="NCacheServer.EnableCacheLastAccessCount" value="false"/>
EnableCacheLastAccessCountLogging enables Logging of Keys into a log file (created under the logs folder). This option would apply only if NCacheServer.EnableCacheLastAccessCount is set "true".
<add key="NCacheServer.EnableCacheLastAccessCountLogging" value="false"/>
Time interval for a key not been accessed for last given minutes. Value is in minutes. A value of 30 would allow the NCache server to collect all those keys that have been idle for the last 30 or more minutes. This option would apply only if NCacheServer.EnableCacheLastAccessCount is set "true".
<add key="NCacheServer.CacheLastAccessCountInterval" value="10"/>
Logging interval to allow logging in multiple intervals. Its value is not in minutes. Its value is several clean intervals after which keys should be logged into the file. CleanInterval is specified under Cache's "Policies" tab. If the value of this variable is "4" and the clean interval is 15(secs), logging would happen after every 60 secs. Interval-based logging allows NCache to perform without any performance degradation despite certain information being collected from core components to perform this action. This option would apply only if:
NCacheServer.EnableCacheLastAccessCountis set "true".NCacheServer.EnableCacheLastAccessCountLoggingis set "true".
<add key="NCacheServer.CacheLastAccessLogInterval" value="40"/>
