Bug ID: 425804
Summary: Command sources for sensors no longer working.
Product: ksysguard
Version: 5.18.4
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: ksysguard
Assignee: ksysguard-b...@kde.org
Reporter: judd.tay...@cpii.com
CC: plasma-b...@kde.org
Target Milestone: ---
SUMMARY
I'm trying to implement some custom sensors for USB attached devices, but the
examples floating around the internet no longer work. For instance, the
simplified example perl sensor below will not run:
#!/usr/bin/perl -w
$! = 1;
print "ksysguardd 1.2.0\n";
print "ksysguardd> ";
while ( <> )
{
if( /monitors/ )
{
print "random/speed\tinteger\n";
}
if( /speed/ )
{
if( /\?/ )
{
print "Random Speed\t0\t0\trpm\n";
}
else
{
my $val = int( rand()*100 );
print "$val\n";
}
}
print "ksysguardd> ";
}
1;
STEPS TO REPRODUCE
1. Save the above as a .pl file
2. On a new ksysguard tab, click file -> Monitor remote machine
3. Add in some name in host field (not necessarily a valid host name)
4. Select Custom command type
5. Enter the file from #1 as the command
OBSERVED RESULT
The host is shown in the sensor browser, but with a warning icon next to it and
no sensor data. There is NO ERROR message indicating any failure. The process
(random.pl) is running in the task manager, but doesn't seem to be executing
anything.
EXPECTED RESULT
Custom sensor field available in sensor browser.
