Blocker api/classes/CTrigger.php : updateReal()
$expressionChanged (and $descriptionChanged) are does not initialize or incorrectly initializes
There is a possibility 'trigger.update' API issue.
Zabbix 3.0.3 Can't Reproduce a problem. ZBX-10226 (r57799) is related to this matter. <- 2.2 needed this fix too
Steps to reproduce (Zabbix 2.2.4, 2.2.11)
1. Create this triggers on frontend page :
'triggerid' => '13567', 'description' : 'Threshold-Over_HDD-/_Usage :Critical' , 'expression' => '{HOST:vfs.fs.size[/,pused].count(#3,90,"ge")}=2'
'triggerid' => '13568', 'description' : 'Threshold-Over_HDD-/_Usage :Warning' , 'expression' => '{HOST:vfs.fs.size[/,pused].count(#3,70,"ge")}=2'
'triggerid' => '13569', 'description' : 'Threshold_HDD-/_Usage :Critical-line' , 'expression' => '{HOST:vfs.fs.size[/,pused].last(0)}>90'
'triggerid' => '13570', 'description' : 'Threshold_HDD-/_Usage :Warning-line' , 'expression' => '{HOST:vfs.fs.size[/,pused].last(0)}>70'
2. Using "trigger.update" via API :
'triggerid' => '13567', 'description' => 'Threshold-Over_HDD-/_Usage :Critical' , 'expression' => '{HOST:vfs.fs.size[/,pused].count(#2,90,"ge")}=3'
'triggerid' => '13568', 'description' => 'Threshold-Over_HDD-/_Usage :Warning' , 'expression' => '{HOST:vfs.fs.size[/,pused].count(#2,70,"ge")}=3'
'triggerid' => '13569', 'description' => 'Threshold_HDD-/_Usage :Critical-line' , 'expression' => '{HOST:vfs.fs.size[/,pused].last(0)}>90'
'triggerid' => '13570', 'description' => 'Threshold_HDD-/_Usage :Warning-line' , 'expression' => '{HOST:vfs.fs.size[/,pused].last(0)}>70'
3. And this expressions result (WRONG) :
Threshold-Over_HDD-/_Usage :Critical {HOST:vfs.fs.size[/,pused].count(#2,90,"ge")}=3
Threshold-Over_HDD-/_Usage :Warning {HOST:vfs.fs.size[/,pused].count(#2,70,"ge")}=3
Threshold_HDD-/_Usage :Critical-line {HOST:vfs.fs.size[/,pused].count(#2,70,"ge")}=3
Threshold_HDD-/_Usage :Warning-line {HOST:vfs.fs.size[/,pused].count(#2,70,"ge")}=3
