How to clear Web acceleration cache?
So I have been trying to clear the web acceleration profile cache on applications and have ended up deleting the profile instead with this command: DELETE '/mgmt/tm/ltm/profile/web-acceleration/~partion~app.app~optimized-caching_profile' Can someone please help with the right commands for this? Also tried to clear all with DELETE '/mgmt/tm/ltm/profile/web-acceleration/all' not sure it worked as the only response is null "" Any references to better documentation or understanding would be greatly appreciated.
High consumption of CPU after upgraded to 11.6.0
Hello, could anyone help me? We have a couple of Bigip running with LTM, Webaccelerator and ASM, that is running in Failover. Yesterday we upgrade the version from 11.5.1 Build 5.0.147 to 11.6.0 Build 3.0.412 but now I'm getting high CPU consumption and in less than 24 hours after upgrading my active Bigip did fail over. Follow bellow the messagens logs when the problem starts: Wed Feb 11 15:12:53 BRST 2015sod[6881]Offline Wed Feb 11 15:12:53 BRST 2015sod[6881]Offline for traffic group /Common/traffic-group-1.

Queuing traffic in iRules - advisability!!
I posted this codeshare recently which is a pair of iRules which queue requests in front of WAM with the idea being that when they are released the request will be in cache and served from cache https://devcentral.f5.com/wiki/iRules.Web-Object-Request-queuing-for-WAM-v10-x.ashx, using the entries in the session table as kind of semaphore to signal when a page request was in progress. The purpose of this was to reduce spike load on the backend servers when page objects expire from WAM cache, as the backend system is a CMS for which assembling new pages is relatively CPU-intensive. I haven't deployed this to a production system yet but it's very close to it. I today stumbled upon a few discussion threads from a few years ago which have alarmed me, to say the least, all saying DON"T do what I have done ie;- https://devcentral.f5.com/questions/irule-that-waits21872 https://devcentral.f5.com/questions/queue-traffic-after-session-rate-limit-reached Now, I suspect (hope) that the introduction of command suspension http://support.f5.com/kb/en-us/solutions/public/12000/900/sol12962 will have alleviated some if not all concerns on this front, but I'd like some prompt advice on the topic!!AAM: how to cache home page? (when path = /)
I'm trying to figure out how to cache pages if the request doesn't contain a file name (e.g. http://www.domain.com/)..) I assumed that the MIME-type of the Object Type (under Policies) would classify HTML-pages as such, but it looks like this doesn't cover requests without a matching file extension. What am I missing?
Configuring SNMP traps to use a source IP address
Hi all, I am trying to configure some customs SNMP Traps but these are always sent through an ip address other than the management. Even when i configure the snmp trap source ip address explicitly using modify /sys snmp trap-source , all traps are sent using a self ip as source. I am using logger -p local0.warning "Pool /Common/web_pool443 member /Common/10.10.0.100:80 monitor status node down. [ was up for 0hr:1mins:33sec ]" to reproduce the snmp trap and i monitor traffic with tcpdump on all interfaces (including management interface) on port 162. The version is 11.6 HF4 Any ideas?Clearing of RAM-Cache or Web Acceleration profiles
I need a way to clear the web cache from off box. I'm playing around with PowerShell for iControl but don't see any ramcache related commands listed. I found a sample script the references the 'Get-RAMCacheEntry' command but this doesn't seem to exist any more. Basically, I need a good way of doing what this command does without giving my application people CLI access to the big-ip. tmsh delete ltm profile ramcache [cache profile name] Ideas? Thanks, PatrickError Code 10061: Connection refused
I am trying to access a set of servers configured to be load-balanced by F5 through an ISA proxy. I get this error message from the proxy each time I try to access it: Error Code 10061: Connection refused Background:The server you are attempting to access has refused the connection with the gateway. This usually results from trying to connect to a service that is inactive on the server. Please, how can I resolve this problem? Thank you in advance
