| + There is also a utility to read the logged data through the SICS server. The command syntax |
| + is: |
| + {{{ |
| + graph <start time> <end time> np <number of points> <variable> <variable> ... |
| + graph <start time> <end time> text <variable> <variable> ... |
| + }}} |
| + where |
| + |
| + ;<start time> <end time>:start and end time in seconds. Negative or small values (lower than one year) are relative to the actual time. Large values are treated as unix time values (seconds since 1970-01-01:00:00:00 UTC). |
| + ;<number of points>:the maximal number of points to be read. If the the number of points is less than the interval duration divided by the logging period, the data is compressed. |
| + ;<variable>:the variable name or object parameter name (<object>.<parameter>). |
| + |
| + The second form with the keyword {{text}} does not compress, and is mainly used for text |
| + variables. |
| + |
| + The returned list has the following syntax: |
| + |
| + *first line: the actual time in unix format (relative times are related to this value) |
| + *then, for every variable |
| + **variable header:\\ |
| + {{*<variable name> exact <exact flag>}} |
| + **first datapoint:\\ |
| + {{<unix time> <value>}} |
| + **further datapoints (may appear many times, up to the number of points specified):\\ |
| + {{<seconds since last datapoint> <value>}} |
| + *end mark:\\ |
| + {{*<compressed> <overflow>}} |
| + <compressed> is 0, if no compression appeared, 1 else\\ |
| + <overflow> should be 0, else an internal error occur (might be removed later) |
