[asterisk-users] Asterisk -rx, how expensive is it? Should you avoid "spamming" it?

[Mikael Fredin]

Thank you, that's very useful information! Does the same go for issuing a
"sip show peers" through the AMI? And do you know where I could find
information of what asterisk versions may use cached information instead?

What would you suggest be better ways to monitor asterisk information?
