yes. when i explicitly specifiy all dependencies it works too.
the first variant i tried was the following:
watch a
service a1
description ping
interval 5m
monitor fping.monitor
period wd{Mon-Sun} hr{2} min{10-59}, wd{Mon-Sun} hr{3-1} min{0-59}
alert mail.alert someone@somewhere
alertevery 1h
service a2
description dns
interval 5m
monitor dns.monitor
period wd{Mon-Sun} hr{2} min{10-59}, wd{Mon-Sun} hr{3-1} min{0-59}
alert mail.alert someone@somewhere
alertevery 1h
watch b
service b1
description ping
interval 5m
monitor fping.monitor
depend a:a1
dep_behavior a
period wd{Mon-Sun} hr{2} min{10-59}, wd{Mon-Sun} hr{3-1} min{0-59}
alert mail.alert someone@somewhere
alertevery 1h
watch c
service c1
description ping
interval 5m
monitor fping.monitor
depend b:b1
dep_behavior a
period wd{Mon-Sun} hr{2} min{10-59}, wd{Mon-Sun} hr{3-1} min{0-59}
alert mail.alert someone@somewhere
alertevery 1h
watch d
service d1
description ping
interval 5m
monitor fping.monitor
depend b:b1 and a:a2
dep_behavior a
period wd{Mon-Sun} hr{2} min{10-59}, wd{Mon-Sun} hr{3-1} min{0-59}
alert mail.alert someone@somewhere
alertevery 1h
i only want to send alerts of c:c1 if b:b1 and a:a1 are working and no
alerts if they fail. but that didn�t work.
i had to remove the dependecy in b:b1, then it worked. the same for d:d1. i
removed the dependencies in all parent services. the it worked.
