T4 friend to monitor VMS mailbox performances

[Guinaudeau]

hi,

i am looking for a T4 friend which would monitor the mailbox operations under a VMS machine.

i am looking for a VMS utility to monitor a certain list of mailboxes
on one machine for (at least the operation count rate, optionally the reference
count current value)

i want the output to be T4 formatted, so to visualize with TLViz and correlate with other T4 performance data.

concerned systems are in first approach VMS 7.3-2, but it would be nice to run it under any VMS 7 and 8 next.

i googled and thought i will find something like that, but i did not. missing the correct link ?

at http://vmspython.dyndns.org/t4web/ I see among all the items you may select MON.IO Mailbox write rate.

You will need Python, but movable Python for Vms is now available, you may install Python only for you using the LD devices at

http://vmspython.dyndns.org/anonymous/kits/axp/images_ld/
(if you have an Alpha) or
http://vmspython.dyndns.org/anonymous/kits/ia64/images_ld/
(if you have an Itanium)

python + LD can be used for our own needs under test platforms, but i want to port this tool to customer sites to look at their performance data. the tool should run stand-alone in a batch minimal environment.

some customers do not want to have additional SW just to run this monitoring.

someone suggested me to write a tiny DCL script to do this and this may be the better way. i can better adjust to my needs (performance concerns not every mailboxes on the machine).

just questioning whether a freeware would exist, T4 friendly oriented, which covers such a need.

nevertheless thanks for the info, i forgot this python env, and it could be used to look at the T4 data later on our site.

This could be done in DCL with F$GETDVI collecting the data.

I suppose it could be one file with the usual T4 header then

datetime,mb1 op rate, mb1 ref cnt,mb2 op rate,mb2 ref cnt, mb3 op rate, mb3 ref cnt

etc where mb1 is the first mailbox you are interested in, mb2 is the second and so on.

The sda extension mbx$sda is in sys$examples on any Vms system, I do not remember exactly if it suits your needs.

The source file, MBX$SDA.C, is provided in SYS$EXAMPLES.

Louis,

it would be easy to write a little DCL procedure to capture the desired data using F$GETDVI and output them into a T4-style .CSV file, to be used to analyze this data using TLVIZ to view it in parallel with the default T4 data being collected.

There are lots of people around with enough DCL and T4 experience, who would certainly be able and willing to write such a simple T4 collector, but maybe not in their spare time ;-)

MBX$SDA is more of an example to show how to write SDA extensions. It does capture MBX information (SDA> MBX SUMMARY) in a format to be easily post-processed by a DCL script

i will write a simple DCL script for the mailbox monitoring adapted to our needs (= mailboxes of our application first).

thanks for the MBX$SDA i would have forgotten. it may be usefull in a daily survey job i got to collect some informations about each system.
