Ports down in Nagios whereas Up on network switch end

Okay, so the backend Nagios Core is showing properly, it looks like it's probably the DB that isn't being updated (nagios_servicestatus):

Please try this:

Code: Select all

yum reinstall php-pgsql
yum install php-pdo-dblib php-process 
systemctl restart nagios httpd crond

Then make sure that this command:

Code: Select all

tail -Fn0 /usr/local/nagiosxi/var/cmdsubsys.log

Is not showing these errors anymore:

Code: Select all

PHP Warning:  PHP Startup: Unable to load dynamic library 'pgsql' (tried: /usr/lib64/php/modules/pgsql (/usr/lib64/php/modules/pgsql: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/pgsql.so (/usr/pgsql-9.6/lib/libpq.so.5: undefined symbol: simple_string_list_member)) in Unknown on line 0
PHP Warning:  PHP Startup: Unable to load dynamic library 'pdo_pgsql' (tried: /usr/lib64/php/modules/pdo_pgsql (/usr/lib64/php/modules/pdo_pgsql: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/pdo_pgsql.so (/usr/pgsql-9.6/lib/libpq.so.5: undefined symbol: simple_string_list_member)) in Unknown on line 0

Send the output of this command as well:

Code: Select all

mysql -uroot -pnagiosxi nagios -e 'show create table nagios_hoststatus; show create table nagios_servicestatus;show create table nagios_objects; select count(*) from nagios_objects;'

Hi ,

As suggested, I did reinstallation of pgsql and check the output of "tail -Fn0 /usr/local/nagiosxi/var/cmdsubsys.log" still getting

Code: Select all

PHP Warning:  PHP Startup: Unable to load dynamic library 'pgsql' (tried: /usr/lib64/php/modules/pgsql (/usr/lib64/php/modules/pgsql: cannot open shared object file: No such file or directory), /usr/lib64/php/modules/pgsql.so (/usr/pgsql-9.6/lib/libpq.so.5: undefined symbol: simple_string_list_member)) in Unknown on line 0

Refer the attached file for requested output.
