[lvs-users] LVS API?

Hello,

Are there any API (prefer in Perl/PHP) so Round-Robin weight can be
changed on the fly from remote server.

I need this to auto-balance server weighting without sysadmin change
them manually everytime.

Also, any web-based LVS front-end recommended?

Thank very much.

no. You'd need to do it with ssh.

a few have been written. look in the HOWTO. They're all
written by one person who posts the code and no-one seems to
use them and then they aren't maintained.

As Joe points out, no. The API is either the command line, or the
underlying ip_vs library which can be called by other applications in
their code.

Then you should consider using keepalived to manage your system, which
can adjust weights according to the result of scripts called by the
health check process.

Hi,
I got the same problem which I solved using the misc_dynamic option of
the keepalived daemon misc_check feature.

Regards,
Paolo.
