Hash: SHA1
New patch attached, which is merely a bundle of all patches
(cherry-picked changes from master with some conflict fixes)
The NEWS and tests (plugins/t/* and plugins/tests/*) hunks aren't
absolutely needed, but I strongly recommend applying them because:
1. They don't affect at all the final release
2. They're required for a successful tests run
The commit message is:
check_snmp: Remove that is_numeric madness
Original patch to make Timeticks works as in check_snmp v1.4.14, it turns
out is_numeric isn't so useful and treating all types as numeric works
best for backwards-compatibility. This is how it used to work in 1.4.14.
As a special case, I also make calculate_rate look up for numeric values
as it would otherwise return the last value instead.
[Patch attached]
