-==== 'All' vs 'Light' vs 'Full' panels ====
-=== Light panels: ===
-{{ :xnorit:public:0k_freezermonitoring:grafana_wiki2.png?400|}}
-A panel named with 'Light' provides the user with a quick and simple to read overview, with the drawback that it only contains an limited amount of data and information.
-Each monitored freezers is provided with a small indication of the current temperature. Beneath the temperature is a small chart visible.
-If a temperature is out of range (As seen for freezer T_209), both temperature and chart change color.
-The default color setting is:
-  * temperature below -100 = Blue
-  * temperature in-between -100 and -60 = Green
-  * temperature in-between -60 and -50 = Orange
-  * temperature in-between -50 = Red
-Below the temperatures there is a field visible containing "Freezer health".
-If a freezer supports this function, the freezer health will detect interruptions in freezer operation (breakdown/failure/AC loss).
-Using the default settings, this detection happens within 1 minute.
-The shown percentage is a calculated average over the selected time-span inside Grafana, see <color #ed1c24>panel settings</color> for more information.
-=== Full panels: ===
-{{ :xnorit:public:0k_freezermonitoring:grafana_wiki4.png?400|}}
-A panel named with 'Full' provides a more thorough overview of each recorded freezer data, with the drawback of lessened readability.
-At the left an 'alert overview' is visible, providing an direct overview on freezers with possible issues.

-For a full screen view of only one chart, click the drop-down menu on top of the chart and click 'view' (see picture).
-{{ :xnorit:public:0k_freezermonitoring:grafana_wiki9.png?800 |}}
-The charts contain following information:
-  * Freezer health, shown on the right y-axis (purple/pink)
-  * Room temperature, shown on the left y-axis (Orange) (Measured within the monitor enclosure resulting in a ~5°C increase in temperature).
-  * Freezer temperature, shown on the left y-axis (Blue)
-  * Mail alert threshold, shown on the left y-axis (Red)
-If the freezer temperature is below the set threshold, and the freezer health is above 50%, the hearth above the chart will indicate a green color.
-{{ :xnorit:public:0k_freezermonitoring:grafana_wiki5.png?800 |}}
-If the freezer temperature is above the set threshold, and the freezer health is below 50%, the hearth above the chart will indicate a red color (and is broken).
-{{ :xnorit:public:0k_freezermonitoring:grafana_wiki6.png?800 |}}
-If the preset alert conditions are met, the alert mode will first go in 'pending' state. The pending state is tagged on the chart using an orange vertical line.
-In case that the 'pending' problem is not resolved after (by default) 5 minutes, the state evolves to an alert, this is when en email is send as warning. An alert is tagged on the chart using an red vertical line.
-{{ :xnorit:public:0k_freezermonitoring:grafana_wiki7.png?800 |}}
-When the monitor system operation is interrupted, a gray vertical line is tagged on the chart (NO DATA). This indicates a possible issue with the monitoring system itself. For example when AC power is interrupted.
-{{ :xnorit:public:0k_freezermonitoring:grafana_wiki8.png?800 |}}
-When a problem is resovled, this is indicated with a green line. By default when a problem has been resolved, a secondary mail is send as conformation.
-=== All panels: ===
-A panel named 'ALL' contains a 'Light' representation of all connected freezers at a given site.
