Collect all partition pool member stats with tmsh

Code is community submitted, community supported, and recognized as ‘Use At Your Own Risk’.

Short Description

This solution resulted from a question on how to get all the stats from pool members of all partitions in one iControl REST method call. I couldn't figure out a solution to that just with iControl REST, so I created a tmsh script to collect the stats and a python script to run that script and download the stats.

Problem solved by this Code Snippet

Eliminates the need to make a lot of REST calls to get the pool member data

TMSH script (latest here)

proc script::run {} {

    # where to store the data - /shared/images
    set fp [open "/shared/images/poolstats.csv" w+]

    tmsh::cd /

    puts $fp "pool,member,ss.bits-in,ss.bits-out,ss.pkts-in,ss.pkts-out"

    # iterate through pools
    foreach pool [tmsh::get_config /ltm pool recursive] {
        set pl [tmsh::get_name $pool]
        foreach obj [tmsh::get_status /ltm pool $pl detail] {
            foreach member [tmsh::get_field_value $obj members] {
                set mbr [tmsh::get_name $member]
                set ss_bit_in [tmsh::get_field_value $member serverside.bits-in]

                set ss_pkts_out [tmsh::get_field_value $member serverside.pkts-out]
                puts $fp "$pl,$mbr,$ss_bit_in,$ss_bit_out,$ss_pkts_in,$ss_pkts_out"
    # close file
