conkw documentation - OshiGrabber

This is the system grabber using the OSHI API. This API is built on top of JNA and can drill down pretty deep in the host system. It should be noted that it is much more expensive to use than ProcGrabber, but it works on non-linux systems.

This documentation will not drill down on OSHI and its system representation. For more details on that, please refer to the OSHI documentation.

• Full name: net.pieroxy.conkw.webapp.grabbers.oshi.OshiGrabber
• Default instance name: oshi

Use cases

• You want to monitor system metrics out of your Mac, Linux or Windows machine. That's CPU, HDD, SSD, Network, battery, etc.

Configuration

{
  "implementation":"net.pieroxy.conkw.webapp.grabbers.oshi.OshiGrabber",
  "name":"oshi-processes",
  "parameters": {
    "toExtract":["processes"],
    "detailedDataDelay":"5s",
    "staticDataDelay":"86400"
  }
}

• toExtract: you can specify one or more class(es) of data to extract. This will considerably improve performance if you don't need some of the most expensive extractions on all the time (See processes and services below)
• detailedDataDelay: The delay at which the most expensive data is extracted, instead of once every second. That applies to processes and services below. Default is 5 seconds.
• staticDataDelay: The delay at which the "static" data is extracted. This is serial numbers, makes and models of various pieces of hardware on your computer. Default is one day.
• See here for the delay format

The default configuration includes three of these grabbers, one configured for processes, one for services and one for the rest. Note how having three instances allows to benefit from the whole range of metrics while only consuming resources for the ones you actually have a dashboard open.
