![]() Each photon contains a certain amount of energy. Radio waves, gamma-rays, visible light, and all the other parts of the electromagnetic spectrum are electromagnetic radiation.Įlectromagnetic radiation can be described in terms of a stream of mass-less particles, called photons, each traveling in a wave-like pattern at the speed of light. The biggest gamma-ray generator of all is the Universe.Īre radio waves completely different physical objects than gamma-rays? They are produced in different processes and are detected in different ways, but they are not fundamentally different. ![]() Gamma ray: Doctors use gamma-ray imaging to see inside your body. Hot gases in the Universe also emit X-rays. X-ray: A dentist uses X-rays to image your teeth, and airport security uses them to see through your bag. "Hot" objects in space emit UV radiation as well. Ultraviolet: Ultraviolet radiation is emitted by the Sun and are the reason skin tans and burns. Fireflies, light bulbs, and stars all emit visible light. In space, infrared light helps us map the dust between stars. Infrared: Night vision goggles pick up the infrared light emitted by our skin and objects with heat. Microwave: Microwave radiation will cook your popcorn in just a few minutes, but is also used by astronomers to learn about the structure of nearby galaxies. Radio waves are also emitted by stars and gases in space. You could add in another if/then statement so that if it met other criteria use a different $MAIL -s entry.Radio: Your radio captures radio waves emitted by radio stations, bringing your favorite tunes. $MAIL -s "A $SEV alarm has occurred on $SERVER (Model Name=$MNAME)(Model Type=$MTYPE)" $RCVRS < /tmp/set_alarm.$PID This is configured in the SetScript for the Notifier process ($SPECROOT/Notifier/SetScript) via this line: If you would like to have a different subject in the email sent to different recipients: Please reference the " AlarmNotifier" section of the documentation for more information. If emails fail to send please see your system admin to ensure sendmail is set up correctly for your environment. You should see the settings you used.ĪlarmNotifier utilizes the email utility configured for the Operating System, typically this is sendmail. In the HKEY_CURRENT_USER/Software/SMail folder, these are the entries from the example. Once this command is run you can run regedit and search for SMail. ![]() mail.exe -h snmtp.ca.com -u spectrum -m ca.com Open a command prompt in Windows and enter the following command where is the hostname of the smtp mail server, is the return e-mail address, and is the domain name in the $SPECROOT/NT-Tools/SRE/bin directory:Īs an example mail -h smtp.ca.com -u spectrum -m ca.com To configure Simple mail please do the following:ġ. This will also need to be configured for AlarmNotifier to successfully send an email. Verify AlarmNotifier is now a running processĬA includes Simple mail for use in sending emails. Starting in Spectrum 10.4.2.1, script will now also stop the SpectroSERVER and Archive ManagerĨ. ![]() As an alternative, use the processd executable to restart the service and this will not stop the SS and ArchMgr. NOTE: Starting from 10.4.2.1 / 20.2.3, the restart will now also stop the SpectroSERVER and Archive Manager. Enter the following command to restart processd and pick up the changes made to the ALARMNOTIFIER.idb file: On Linux or Solaris, su to the root userĦ. On Windows, start a bash shell by running "bash -login". Out of the box you can see AUTORESTART is already set to yes. $SPECROOT/lib/SDPM/partslist/ALARMNOTIFIER.idb fileģ. To ensure AlarmNotifier is always running, you can configure processd to automatically start AlarmNotifier at processd startup and to restart AlarmNotifier should processd see the AlarmNotifier process has stopped.ġ. If you are using the default scripts it is recommended to take a backup of the Notifier and lib/SDPM/partslist folders before upgrading.įor more information on Alarm Notifier please reference: Custom named script files remain untouched. NOTE2: During an upgrade the default AlarmNotifier script files will be overwritten and set back to the defaults. Ensure the files are not saved with extensions like. NOTE: When using editors to modify these files, be sure to save the files in ascii text format only. Modify the ClearScript and UpdateScript files using these same instructions. Edit the $SPECROOT/Notifier/SetScript file To configure AlarmNotifier to send an email when an alarm is received.ġ.
