AltocumulusiRule [string range...] not chunking data properly
I have an irule (much of which I found here) that is to gather some much needed troubleshooting data I need in regards to the headers and payload I have coming in. The payload is obvisouly too large...
In fact I have just grabbed this from an iRule i recently wrote. Almost the same, with fixed values. Note the end is 99 but the increment is 100. As you say, string range is zero-indexed
for {set start 0; set end 99} {$start < [HTTP::payload length]} {incr start 100;incr end 100} { log local0.debug "[string range [HTTP::payload] $start $end ]" }

MVPHello, There are a lot of community articles about this for example https://community.f5.com/t5/crowdsrc/log-http-request-and-response-payload-via-hsl-and-locally/ta-p/284294 . My last idea is to send the logs as I mentioned to external log server as the limit is 1024 for an http request and the different chrunks seem to be considered a part of a single request as F5 needs to gather all the chrunks for inspection by for example the WAF policy etc.
Log4j2Unfortunately logging to an HSL pool is not an option for me - that's more configuration and setup time than I've alloted for the details this irule should provide that I need for about a 24hr period.
I just can't figure out why it's omitting a chunk of data, otherwise it works perfectly
Looks like the post you linked is almost identifical to what I have except his loop isn't nested under an 'if' statement. I could give that a try
