API calls to be handled only within one session

Hello all,

I am working on some script and I would like to have some questions sorted out about API performance and best practise. I am on R80.30 MDS and using API version 1.5.

My idea is to have opened only 1 session (via login), store session into a variable (or file) and during the entire script, working only with this one session. Means, no other sessions will be opened as I don't want to have an additional load on the machine for login and logout operations.

If I am using "-r true" for any API calls (let's say show domains), will it mean that in the background there will be a new login and logout ?

At the moment I am struggling with "show packages" for a specific domain and the fact that -s parameter isn't working.
The code looks like that:

#!/bin/bash mgmt_cli login user "aa" password "aaaa" --format json > sid.txt mgmt_cli show packages -d "My_Domain" -s sid.txt --format json mgmt_cli logout -s sid.txt rm sid.txt

And it doesn't give me the desired output - packages of the domain "My_Domain".
In case I use the following syntax, all is working fine (note -r true parameter instead of -s sid.txt):

#!/bin/bash mgmt_cli login user "aa" password "aaaa" --format json > sid.txt mgmt_cli show packages -d "My_Domain" -r true --format json mgmt_cli logout -s sid.txt rm sid.txt

But the working solution will result that I will have 2 sessions opened, right ? And I want only 1, not more.

What I am missing here ?

Thank you.

A couple things:

1. mgmt_cli -r true will create a session per command and should be avoided if you're issuing a lot of commands at once.
2. A session is only valid in the context of a given domain, which means if you want to do something in a different domain, you will need a different session.

In other words what point 2 says, you need to put the -d <domain> in the login line, not in the line with the actual commands.

So that was a missing bit, thank you 🙂

If I have 20 domains, do I need to iterate over all domains and login into each and every domain separately ? There is no way to login like "super login" which login session will be valid for all domains ?

You are correct, you need to login to each and every domain separately as when you login without domain, you are in the Global domain.

Not 100% correct.

If I am not mistaken on MDS a API command without domain accesses the system domain.

Global needs to be specified as any other!

I stand corrected.

I am sorry that I will use my thread for some other question:
In HA MDS, how is it working if I want to get data from Active management? Do I need to do it like I did in R77.30 - mdsenv <DOMAIN> and check if CMA (domain) is active using FwIsActiveManagement?
Or in R80.x it doesnt matter on which MDS I am working, as both have the same data ?
