What parameter sections can be checked to find out the cause of slow GUI access?
some GUI access devices in customers experience slow access, in some open case opportunities, the cause is because the tomcat memory is lacking and needs to be improved. after being improved, then access becomes better. from that, are there any parameters that can be checked related to the use and availability of a parameter related to this? Thank you

Tampermonkey - BIG-IP Configuration UI Enhancements for APM
Problem this snippet solves: This script was designed in order to enhance the existing APM section of the BIG-IP Configuration UI. It was originally written for v11.5.1, but should work for many earlier and later versions as well. Enhancements Adds a link on the Manage Sessions page for each session that will display the APM logs and Session Variables reports in a new window Adds an Apply button on the Access Profiles page for any profile whose changes have not yet been applied The latest version of this codeshare can be found on Github at the link below. I have another script like that designed to help with the LTM sections of the BIG-IP Configuration UI, and this was pulled out of that in order to allow for modular enhancement. Known Issues If you're on a slow connection, clicking the show button to open the session variables may not bring up the tab. If this happens, either try again, or refresh the page after it opens and that should help. This is due to the way I had to get the session variable to open. Version History v1.0 - Initial version with Manage Sessions link to Session Variables report and Access Profiles apply button for policies that need to be applied. Inspiration Credit: Patrik Jonsson's Web UI Tweaks codeshare How to use this snippet: Instructions The Tampermonkey Chrome extension needs to be installed for this script to work Once installed, click on the Tampermonkey icon and click Dashboard Click the new script button and set the Update URL field to https://github.com/jangins101/F5/raw/master/F5%20UI%20Enhancements%20for%20APM.js You can also copy the whole document linked below into a new Tampermonkey script and save it Click Save and then click the value in the Last Updated column for that new row. This should update the script Security note: In case you would not want to have the script automatically update when a new version is released, you can remove the @updateUrl line. Another option would be to fork the Github repository and then use your own copy of it. Code : https://github.com/jangins101/F5-Tampermonkey-Scripts/blob/master/F5%20UI%20Enhancements%20for%20APM.js Tested this on version: 11.5
Lost Access to GUI - VM
Hi everyone, Hoping to get some help.I have a little test machine GTM/LTM on a trial license which I use to practice and test out deployements on.I've been using it for a good month running off of vmware workstation.It's been working flawlessly until today.I typically shut it down when not in use.When I attempted to use it today, for some reason, I canot access the GUI.I simply get "this site can't be reached". x.x.x.x refused to connect. I'm able to log on to the box through the terminal and putty (ssh).I checked the config to ensure that everything is still in tact, and it is. I'm able to ping and access the mgmt interface, and obviously as I'm ssh'd in to it, the config looks fine and identical to how I left it the previous time I used it. At bootup, the system goes in to INOPERATIVE state. There are a few startup messages: kernel: ibrs changed from 1 to 0 EXT4-fs error (device dm-1): ext4_mb_generate_buddy:757: group 17, block bitmap and bg descriptor inconsistent: 23131 vs 23132 free clusters Re-starting named After the re-starting of named, it changes from INOPERATIVE to Active. I have tried restarting the box and virtual machine multiple times.I tried restarting tomcat and httpd processes.I get the following message when restarting httpd httpd[11494]: [ssl:emerg] [pid 11494] AH01874: Could not initialize session cache. Exiting. I typically use chrome, but tried mozilla, same issue. Anyone have any ideas on a fix? Thanks
Failing to login to GUI with admin account
I'm experiencing a really strange issue with my Virtual F5 LTM. I'm running BIG-IP 11.6.1 Build 1.0.326 and since two weeks I'm not able to log into the GUI anymore. Neither with the admin account, nor with any other account. The CLI is no issue, I can log in there without any problems. I keep seeing the follow logs in de secure.log: Nov 10 21:09:37 localhost alert httpd[20065]: PAM Couldn't open /var/log/pam/tallylog : Permission denied Nov 10 21:09:37 localhost alert httpd[20065]: pam_tally2(httpd:auth): Error opening /var/log/pam/tallylog for update: Permission denied Nov 10 21:09:39 localhost info httpd(pam_audit)[20065]: User=admin tty=(unknown) host=10.128.1.1 failed to login after 1 attempts (start="Thu Nov 10 21:09:37 2016" end="Thu Nov 10 21:09:39 2016").

Not sure if it's related, but I find it strange that PAM couldnt open the tally log. The file is definately there and permissions seems to be correct. Things I've tried so far without result: resetting the admin password to default creating a new user account with admin rights loading default config set full rights to the tallylog file. uploaded the config to iHealth, no really strange things beside a load of failed loging attempts tried different browsers. Maybe someone else has any suggestions what to do next? I'm kinda stuck now... Thanks in advance.DNS Tab not appearing on device
Hello, I am encountering an issue where the DNS tab is not showing up in the management GUI. I have the DNS module licensed and provisioned but the DNS tab disappeared after provisioning. I have tried rebooting the system, de-provisioning and re-provisioning all modules, and restart certain daemons. Has anyone else encountered this issue or can anyone provide possible solutions?
Web UI search for objects that do NOT contain a word
In the BigIP web user interface. How do I do a search where I look for objects that dont have a word in the name. For example, how do I do a search in Local Traffic > Virtual Servers > Search field box > search for all objects that do NOT have the word 'test' in the object name?
Best tools for network toubleshooting?
Hi, I am looking for any hints about tools used by more experienced members here. I am not hard core network geek so GUI based tools are proffered (and freeware) - for Windows and Linux platforms. What I already know and use: Wireshark - pretty obvious :-). I am using F5 plugin but wonder what other plugins are really useful in real life work? Ostinato - seems to be very nice packet replay and crafting tool - will have to figure out how to replay captured traces but even without this knowledge it's very promising Network Emulator Toolkit (Windows) - seems that it would be great for simulating different type of links (like changing RTT, packet loss, etc.) - just installed it and have no chance to play around. TCP/IP Builder (Windows) - simple yet very useful tool to play with TCP/UDP connection setup netem (Linux) - exception from my own rule - command line tool - but seems to be quite powerful in the same area as Network Emulator Toolkit Piotr
