- | There is an option | + | To get data from graph log, it is necessary |
- | To obtain entries from the meters, you must perform follwing GET request on a URL | + | Also, instead of specifying |

- | + | ||
- | Also, in the headers, you must specify the desired data exchange format. Currently, only the JSONformat | + | X-WH-SLICES is the number of values. The time interval X-WH-START-X-WH-END will be divided into X-WH-SLICES of equal intervals and the system will take the most detailed values for each of them. |
+ | X-WH-SLICES should be chosen based on the necessary detail of the graph. So, if you need to build a graph 800 pixels wide, then it makes no sense to choose more than 800 values from the log. And sometimes there will be enough 200-400 values depending on the width of the line on the graph. | ||
+ | |||
+ | To speed up the operation, the system can store the averaged values of the registers for different intervals (1 minute, 2 minutes, 5 minutes, 15 minutes, 1 hour). In the configuration of each register, you can specify the required detail of the stored data. Depending on the selected time interval and the number of values, the system will attempt to take data from the most appropriate table of averaged values. or from the register register (if it is included for the specified register) | ||
