How to test APM access policy locally?
Very new to BIG-IP. I have downloaded the BIG-IP VE and imported it into VirtualBox. Followed the basic configuration mentioned here https://f5.bravais.com/s/vf4XckakhbTbCRUwa2sb I created an APM access policy to use AD. But is there any way to test it? Some internal URL which simulates the real world behavior? As I am on VBox, any virtual server I create, is directly accessible from local. How do I get BIG-IP into the picture?
Throughput per virtual server
Hi! Not quite sure if my question fits this forum, but I'm trying anyway :) I'm trying to measure performance through our LTMs. Is there any way to get throughput numbers per virtual server? The default graph in the dashboard gives a good indication of the total traffic, but it would be nice to be able to drill down to a specific vip. Is it perhaps possible to query with snmp? /Niklas
Performance of an external datagroup versus a local datagroup?
Hi, Is there any expected difference in performance of a ~10k list of networks/hosts if the datagroup is defined in an external file versus locally, directly in the bigip.conf? This is for 9.4.8 if it matters. I'm guessing that the lookup will be handled the same once the datagroup is loaded in memory regardless if whether it's coming from an external file versus the bigip.conf. But I figure I'd ask. I'll also try testing to see if I notice any difference in the timings for the two different datagroups. Thanks, Aaron
iRule test & analysis tool
I'm looking for an iRule analyzer that would allow testing simple traffic scenarios independent of configuring a BIG-IP device. The user would specify values for system variables such as [HTTP:uri] and [HTTP:cookie] and the analyzer would output rewrite url and name of pool routed to , or redirect url , etc. Also would be nice if the tool would also analyzed the iRule for optimum code and performance load testingBIG-IP : simplest way to ensure request is made on new tcp connection
F5 BIG-IP Virtual Edition v11.4.1 (Build 635.0) LTM on ESXi When testing from client browser or shell ( curl ) , what is simplest way to ensure a request initiates a new tcp connection with the virtual-server ( is not sent on any pre-existing connection ) ? I want to ensure my tests are on a fresh connection and irule stack processing starts fresh.6400 Capacity
We are looking to get the most life out of our 6400's. In trending CPU usage using tmstat we see CPU around 55% - 60% during the business day. We have plans to go to v10 but I wanted to know what a good top level benchmark is for CPU on the 6400 runing v9.x? I know it can use 100% but at what CPU level do you start seeing performance issue? Knowing this will help in planning discussions and hopefully move the upgrade to v10 along quicker.What Happens If 6400 Pushed Beyond Its Capacity?
Hi All. I have a 6400 HA pair running 10.2.0 LTM and very recently added ASM with seven ASM policies. Total CPU use varies between ~65% and 100% after enabling ASM. Several of our websites that have ASM policies will experience a 20x increase in traffic later this year. ASM was not part of the picture last season when we experienced the expected spike in traffic to these websites. I am not certain if the 6400 will be able to handle the load with ASM turned on now. What occurs when a dual CPU system running LTM and ASM runs out of CPU? I presume LTM side of things will be alright because my understanding is that TMM grabs one whole CPU when it starts up. I would expect CPU resources for ASM to be the issue point. What is the behaviour one would expect to see with an ASM enabled website in a condition where the BigIP is pushed to 100% CPU use? Does traffic slow down because of ASM processing or does ASM drop some traffic/connections or is ASM possibly rendered ineffective but LTM traffic is not affected? As you might imagine, I am working on building the case for replacing these 6400s with new equipment. I am trying to establish the urgency and what-if scenarios of deciding to leave it as-is vs replacement. Thanks!
Any questions? Post'em
Hi everyone, If you have any questions or comments about the performance report or it's supporting documents, please feel free to post them here. I'm one of the engineers who helped to create the performance report, and I'll be actively monitoring this forum to answer questions. Mike Lowell
