MIDAS PRTG Sensors Addon: Configuration & Usage

Once you've installed the PRTG Sensors addon, simply go to MIDAS Admin Options → Manage Addons → Installed Addons → PRTG Sensors to obtain (or generate) an Authorization Key.

This key helps prevent unauthorized access to the sensor data generated by the addon, and may be changed at any time. If you change this key, your MIDAS PRTG Sensors will stop working until you update the Authorization Key contained within the sensor URL in your PRTG installation.

To start actively monitoring your MIDAS system from within your PRTG installation, first decide which parameter(s) you wish to monitor from the sensor table below:

Sensor Code	Type	Sensor Description
AGE	Integer	Number of days since the release of the MIDAS build you're currently running
ALO	Integer	Number of currently active logins
BAT	Integer	Number of bookings added today
BMT	Integer	Number of bookings modified today
BDT	Integer	Number of bookings deleted today
BTP	Integer	Number of bookings taking place today
DBS	Float	Current database size (in MB)
ERR	Integer	Number of errors in your MIDAS debug log
EST	Integer	Number of emails sent today
FLA	Integer	Number of failed login attempts today
ICT	Integer	Number of invoices created today
LOK	Integer	Number of locked/suspended user accounts
LUP	Integer	Number of days since last MIDAS update check
NBO	Integer	Number of bookings
NCL	Integer	Number of clients
NOR	Integer	Number of organizations
NUS	Integer	Number of users
NVE	Integer	Number of venues
OBR	Integer	Number of outstanding booking requests
SOS	Integer	Number of staff on site
VIS	Integer	Number of visitors on site

Next, construct a URL containing your authorization key and a comma separated list of the parameters you wish to monitor as follows:

https://your_midas_url/prtg.pl?key=authorization_key&sensors=comma_separated_list_of_sensor_codes

So for example, if you wish to monitor the number of current active logins in your MIDAS system ("ALO") and the number of failed login attempts today ("FLA") in a single PRTG sensor, the resulting URL would be:

https://your_midas_url/prtg.pl?key=authorization_key&sensors=ALO,FLA

Next within your PRTG installation, create a new "HTTP Content" Sensor:

In the Sensor Settings dialog, set the following:

• Sensor Name: The name for your PRTG sensor i.e. "MIDAS"
• Script URL: The URL to your MIDAS PRTG Sensors addon you've constructed above, i.e. "https://your_midas_url/prtg.pl?key=authorization_key&sensors=ALO,FLA"
• Value Type: Select "Integer" if you're exclusively monitoring MIDAS parameters which return integer values, otherwise select "Float".
• Number of Channels: IMPORTANT: Set this to the same number of sensor codes present in the comma separated list you constructed for the above URL. In the above example, this number is "2" ("sensors=ALO,FLA")

Click "Continue" and PRTG will create your new sensor:

By default, channels in your newly created sensor will be named "Value 1", "Value 2", etc, however, you can rename these to match the corresponding MIDAS parameters being monitored, via "Edit Channel Settings":

Note: The channel order in your PRTG sensor is determined by the order of comma separated sensor codes passed in the URL you supplied. In our example (where the sensor string "ALO,FLA" was supplied), the first channel being monitored is "ALO" (current logins) and the second channel is "FLA" (number of failed login attempts)

Tip: You can use the same URL (with different sensor codes) to create additional sensors within your PRTG installation and monitor other metrics and parameters of your MIDAS system in separate sensors.
