Steps to reproduce: Apply a template such as "Cisco IOS SNMP" to host.
{$IFCONTROL:regex:"^(Gi[1-2]\/0\/(1[3-9]|2[0-9]|3[0-6]))$"} => 0
Similar to ZBX-18209 Result: Each time a trigger where regex is False (ie interface name Gi1/0/12) the error shown in screenshot is triggered in "Problems" and "Dashboard". No issue if regex is True (trigger is ignored as expected). Expected: No error, triggers normally. |

Still an issue with 6.4.10 |

Slashes shall not be escaped by backslashes in regular expressions. Please correct the provided example to:
{$IFCONTROL:regex:"^(Gi[1-2]/0/(1[3-9]|2[0-9]|3[0-6]))$"} => 0

Yup that worked. Thank you! Would be worth adding to documentation as most regex engines require escaping forward slashes. |
