Ai, I somehow managed to incorrectly configure the path to the
rrdtool.
I figured that out after I replaced
$retval = $Shell->QueryRaw("{$this->RRDToolPath} graph
'{$filename}' {$query_string} 2>&1");
with
die("{$this->RRDToolPath} graph '{$filename}' {$query_string} 2>&1");
in the src/LibWebta/library/Data/RRD/class.RRDGraph.php file,
viewed /
server/statistics.php?
task=get_stats_image_url&farmid=1&watchername=MEMSNMP&graph_type=daily&role_name=_FARM
and then run that command in the terminal.
Tom, thanks for mentioning those 2 vardump lines. After removing those
2 lines and the 3 others that I've mentioned earlier, the load
statistics are working like they should.
