Detailed Description

Periodically queries various system temperatures and other parameters. Makes use of some shell scripts to parse various /cat/proc and utility program outputs. Temperatures are written to a TELEMETRY log.

See VisAOApp_standalone for command line arguments. There are no additional command line arguments for sysmonD.

This is a standalone VisAOApp, so it doesn't depend on MsgD. In addition to the optional standard config options inherited from VisAOApp_standalone this class has the following also optional config parameters:

  • airTemp_serial_no string - the serial number of the QTI temperature probe monitoring VisAO box air temp.
  • joe47Temp_serial_no string - the serial number of the QTI temperature probe monitoring little joe 47 exhaust temp.
  • qtiAmbSerialNo string - the serial number of the QTI temperature probe monitoring ambient temp.

Member Function Documentation

int VisAO::sysmonD::Run ( )
protectedvirtual

Just installs the kill handler and starts pausing and updating.

Reimplemented from VisAO::VisAOApp_standalone.

Definition at line 431 of file sysmonD.cpp.

References VisAO::VisAOApp_standalone::install_sig_mainthread_catcher(), VisAO::VisAOApp_base::pause_time, VisAO::VisAOApp_base::set_euid_real(), TimeToDie, and update_statusboard().

int VisAO::sysmonD::update_statusboard ( )
virtual

Overridden versions should call this as VisAOApp_bas::update_statusboard so the basics are taken care of.

Return values
0on success
-1on failure
