Problem this snippet solves:

Here's a way to monitor your current gtm pools preferred, alternate, and dropped counts using a custom tmsh script.

Code :

cli script watch_gtmPools.tcl {
proc script::init {} {
    set ::pool_ids "" 
}

proc get_stats { resultsArray } {

    upvar $resultsArray results 

    set idx 0
   set objs [tmsh::get''status gtm pool $::pool''ids raw]
   set count [llength $objs] 

    while { $idx < $count } { 

        set obj [lindex $objs $idx]
       set pool [tmsh::get_name $obj] 

        lappend results($pool) preferred
       lappend results($pool) \
           [tmsh::get''field''value $obj "preferred"] 

        lappend results($pool) alternate
       lappend results($pool) \
           [tmsh::get''field''value $obj "alternate"] 

        lappend results($pool) dropped
       lappend results($pool) \
           [tmsh::get''field''value $obj "dropped"] 

        incr idx
    }
}

proc script::run {} {
    for {set idx 1} {$idx < $tmsh::argc} {incr idx} {
       lappend ::pool_ids [lindex $tmsh::argv $idx]
    }

    array set r1 {}
   array set r2 { }

    set interval 2
   set delay [expr $interval * 1000] 

    get_stats r1 

    while { true } {
       after $delay
       get_stats r2
       tmsh::clear_screen 

        foreach { pool } [lsort [array names r1]] { 

            if { [string length [array names r2 -exact $pool]] == 0 } {
               puts "$pool: no sample"
               continue
            }

            set line [format "%-20s" $pool] 

            set s1 $r1($pool)
           set s2 $r2($pool) 

            set idx 0
           set count [llength $s1]
           while { $idx < $count } {
               append line "[lindex $s1 $idx] "
               incr idx 

                set stat \
                   [expr ([lindex $s2 $idx] - [lindex $s1 $idx]) / $interval]
               append line "[format "%-12s" $stat]"
               incr idx
           }
           puts $line
        }

        # use the most recent results as the next previous results
       array set r1 [array get r2]
       array unset r2
    }
}

proc script::help {} {
    tmsh::add_help "enter zero or more pool names" 
}

proc script::tabc {} {
    foreach {pool} [tmsh::get_config /gtm pool] {
       tmsh::add''tabc [tmsh::get''name $pool]
    }
}
}
