The other day I got a report of slowness when using the "Post" button on incident
Turns out this little functionality uses some undocumented api to /angular.do . In this post I go over what I found out about it and how it's not measured like others.
First place I looked at this report is the transactions table syslog_transactions_list.do, transactions to this endpoint seem to not be tracked there or in the new Active Cluster Transactions loading_transactions.do. Which is unfortunate, because that at least shows where the delay is tracked weather it's on a server-side transaction or something on the client or something on the network.
I went ahead asking HI about it;
I have a user who is reporting slowness when they use the Post button below comment/work notes.... I have looked everywhere I can think of to troubleshoot how long that transaction is taking but it's not logged anywhere. I looked at syslog transactions, and the node file browser but nothing seems to track the POSTs to /angular.do as that hits that endpoint.
How can I see server side these requests and what may be causing that delay?
They pretty much told me the way to track this down is to look at the info in the console of the browser as the user.
All these transactions should be captured but it seems ServiceNow doesn't seem to share this opinion.
I've attached (raw JSONP) the HAR record and found a tool online here on https://softwareishard.com/har/viewer.
It looks like it takes some URL parameters as well as some post body;
