sys db provision.memory.asm
Does anyone know how the sys db keys for provision are used? Can they be custom tuned for host/tmm memory allocations? (BIGIP1-NPRD)(cfg-sync In Sync)(/S1-green-P::Active)(/Common)(tmos) list sys db provisioned.memory.asm sys db provisioned.memory.asm { value "2286" } (BIGIP1-NPRD)(cfg-sync In Sync)(/S1-green-P::Active)(/Common)(tmos) list sys db provision.memory.asm sys db provision.memory.asm { value "2286" }
TMOS v14.1.2.1
We upgraded our vCMP pairs from v13.1.1.4 to v14.1.2 and got "out of memory" and "tmm reload" issue. I spent a month with F5 support did not resolve issue. Now we have 2 core and LTM only (we removed AVR) and swap group up to 100% in couple weeks. F5 recommend use 4 cores for LTM only. Most of pair have less then 10Mbits traffic throughput. We are losing faith in F5 :( Does anybody have same issue with v14 code?
How to calculation memory in F5.
Hi, I would like to know how the F5 calculation it's memory cause when I use command 'tmsh show sys performance system detail' I got the following images attached. you can look at yellow text (other memory used in percentage) it's about 54% from all memory in F5. I would like to know what is the formular to calculation that number? If you look at the images in the section memory breakdown Other used is just 6.8GB/50GB it's about 13.5% of all memory. Thank you.healthiness of F5 - help with errors
Dear Gents, I am reviewing /var/log/ltm logs and KPI statistics on two high available F5s running on release 12.1.3. I am looking for root cause of high memory or CPU usages. There are several problems bellow. Q1 First of all other memory utilization is hitting 70 % (tmm memory just 20%). Also CPU usage is hitting over 70% in peaks. Is there any hint how or where to start high memory or CPU usage issue troubleshooting? F5 is used as loadbalancer. There is very low traffic flowing across F5s around 50 Mbps. Q2 There is seen in ltm logs following error: mcpd[7118]: Sync of device group /Common/device-group-failover-2530624eebc7 to commit id 6666 Is it something on which keep eye? Q3 There is error with unreachable pool member and failing monitor ( err f5-A tmm[12726]: No members available for pool /poolX/pool_A ltm 07-31 05:43:50 notice f5-A mcpd[7118]: Pool /part_X/pool_A member /part_www/10.XX.YY.ZZ:80 monitor status down). I can fix it easily but can such unreachable pool member use high CPU or Memory usage? Any advice helping troubleshooting errors above would be highly appreciated. Many thanks Regards Andy
F5 LTM increasing "TMM Used Memory"
Hi. I have a BIGIP run LTM 11.5.1 HF2 only. My TMM Used Memory increasing indefinitely. I believe that the Subsystem xdata is responsible. What is the xdata? I run the command: tmsh show /sys memory | egrep 'Max\ Alloc|xdata' SubSystem Alloc (bytes) Max Alloc (bytes) Object Size xdata 1.1G 1.1G 2048 Thanks, Jayme
