/system routerboard health - where ?

Hello

I have RB511 and RB532
On both MT 2.9.8 is installed.
Where is “health” ? System cannot find this feature.
What can I do for enable HEALTH functions ??

Best regards

There is no such possibility in Routerboards 500 series, becuse CPU MIPS 4Kc V0.10 dont have monnitoring features.
