so i have logs where a log entry is generated when things are bad; and another when it's good. i can typically use 'transaction' to group these together; however, i only care to get information when i get one entry (bad) but not the related other (good).
so i have each event tagged with 'up' or 'down', so i was thinking of doing something where if the last entry is 'down', then i want some output - like in a table by the host.
This isn't too hard. Using the transaction command along with 'startswith' and 'endswith' you want to search on transactions that aren't closed and then output those unclosed (or evicted) transactions "|search closed_txn=0"
Description: Whether to output evicted transactions. Evicted transactions are events that do
NOT match the transaction parameters; for example, the time range is wrong, or the
"startswith" or "endswith" requirements are missing. Evicted transactions can be distinguished
from non-evicted transactions by checking the value of the 'closed_txn' field, which is set to '0' for evicted transactions and '1' for closed ones. A transaction is evicted from memory when the memory limitations are reached.
