Nagvis problem while ajax transaction ...

[xpertech]

when using Nagvis, sometimes it will popup "problem while ajax transaction. is the nagvis host reachable", what could be the problem and how to fix that?

this could happen for several reasons, possibly hitting max mysql connections which could cause httpd threads to stick.

this would be easy to test.

edit /etc/my.cnf
under

Code: Select all

[mysqld]

add

Code: Select all

max_connections=500

then restart mysqld

Code: Select all

service mysqld restart

Hi Scott,

After testing, it failed to restart mysqld?

[scottwilkerson]

it may be mariadb on our system

Code: Select all

systemctl restart mariadb
