<p>
|

apptime provides information about application procedure execution time.
|
|
It is designed to identify long running jobs causing latency as well as
|
|
general high <abbr>CPU</abbr> usage jobs.
|
|
</p>
|
|
<p>
|
|
No information about <abbr>FHEM</abbr> kernel times and delays will be provided.
|
|
</p>
|
|
<p>
|
|
Once started, apptime monitors tasks. User may reset counter during operation.
|
|
apptime adds about 1% <abbr>CPU</abbr> load in average to <abbr>FHEM</abbr>.
|
|
</p>
|
|
<p>
|
|
In order to remove apptime, <kbd>shutdown restart</kbd> is necessary.
