CirrostratusError connecting to virtual server (HTTP header count exceeded)
I have a new pre-prod HTTPS virtual server. One server in the pool, passing health checks, and the virtual server has zero iRules associated to it.
When I run a curl request to the virtual server, the LTM log is returning errors.
curl --location --request GET 'https://10.10.10.10:443' \
--header 'Host: app.example.com'
curl: (56) LibreSSL SSL_read: SSL_ERROR_SYSCALL, errno 54
I get a successful response from the F5 to the back-end server.
Running version 13.1.3.4.

hoolioHi Javier,
I don't think there is a way to modify the running configuration without the sync status being changed through the GUI, the CLI or iControl. Is there a reason you can't either sync the config to the peer or handle it being out of sync?

Hi Hoolio,
I was looking for a way to implement a monitor that could change on the fly the priority / ratio for a node / member. Something similar to dynamic monitors.
It should be nice I could create my own SNMP monitors and being able to monitor OIDs I'd like to.
Kind regards,
Javier Checa.- hoolioHi Javier,
Is there something you want to do that you cannot do with the default dynamic ratio algorithm? Or is the issue that the dynamic ratio algorithm generates a state where the units show the configuration is out of sync?
Aaron - Javier_Checa_41Hi Hoolio,
I'm not concerned about default dynamic ratio algorithm. I'd like to assess the possibility to implement something similar to SNMP monitors (changing dynamic ratios) but with an external script or through iControl.
Thx for your help Aaron. - hoolioYou might get more relevant views in the iControl forum (Click here). But yes, you can poll the pool members directly using SNMP or any other protocol and then modify the LTM pool configuration to specify a new weight for the pool members.
Aaron - Javier_Checa_41Hi Aaron,
the point of the post was.. to modify any dynamic value through cli or iControl but not modifying the configuration.
best regards,
Javier Checa. - hoolioSorry for the misunderstanding, Javier. If you want to modify how LTM processes traffic to the pool, you'd need either use a dynamic load balancing algorithm or modify the configuration. Dynamic load balancing can be done using a plugin or SNMP monitoring of the pool members. Else if neither of these options work for your scenario, you could modify the configuration manually using the GUI or programmatically via iControl.
If I'm still missing your question, can you elaborate on what you're trying to accomplish, what you've tried and what's not working?
Thanks,
Aaron
