Command type[SQL|CMD]|||Description of the test|||Test command|||Expected type value[value|cmd];;;Expected value;;;Test sign[=|>|<|!=|regex];;;Tag[info|error]|||Non expected output

example with SQL command type :

SQL|||Check if the local admin is blocked|||SELECT COUNT(*) FROM centreon.contact WHERE blocking_time IS NOT NULL AND contact_id = 1|||value;;;0;;;=;;;error|||Please see this link : https://support.centreon.com/hc/en-us/articles/10342991678609--User-is-blocked-error-message-on-Centreon-login-page

example with CMD command type with placeholders RESULT_VALUE and EXPECTED_VALUE in "Non expected output" column :

CMD|||Check if cbd service is active|||/usr/bin/env systemctl status cbd | /usr/bin/env grep -Po '(?<=Active:)[^,]*' | /usr/bin/env awk ' { print $ 1 }'|||value;;;active;;;=;;;error|||The cbd service is "RESULT_VALUE", it should be "EXPECTED_VALUE". Please check the logs in this directory /var/log/centreon-broker/

example with SQL command type and cmd for expected type value (to compare the value of a sql request and the value in a file) :

SQL|||Check if hosts is more than license limit|||SELECT COUNT(*) FROM centreon.host WHERE host_register='1'|||cmd;;;nb=`/usr/bin/env grep -Po '(?<="hosts":)[^,]*' /etc/centreon/license.d/epp.license`;if [[ $nb -eq -1 ]]; then /usr/bin/env echo 99999999;else /usr/bin/env echo $nb; fi;;;>;;;error|||https://docs.centreon.com/docs/administration/licenses/#your-epp-license-is-not-valid

example with CMD command type, case for Debian/RHEL OS and regex on expected value test :

CMD|||Check if selinux is Disabled|||if /usr/bin/env grep -q "Debian" /etc/os-release ;then bin="getenforce"; else bin="getenforce" ; fi && $bin 2>/dev/null |||value;;;^(Disabled|NULL)$;;;regex;;;info|||Current mode is "RESULT_VALUE".
