ctwatch(1) User Commands ctwatch(1)NAMEctwatch - watch events in a contract or group of contracts
SYNOPSIS
/usr/bin/ctwatch [-f] [-r] [-v] contract-type... | contract-id...
DESCRIPTION
The ctwatch utility allows a user to observe the events occurring
within a set of contracts or contract types. By default, ctwatch
watches all contracts.
OPTIONS
The following options are supported:
-f Report events starting at the front of the event queue. Normally,
ctwatch reports only events which occur after it has been
invoked. With the -f option, any events that still exist in the
contracts' event queues when ctwatch is invoked (for example,
unacknowledged critical events) are also reported.
-r Reliably watches all messages. Normally, the system may drop
informative events and acknowledged critical events at any time,
so ctwatch isn't guaranteed to see them all. This option may only
be used if the ctwatch is invoked with the {PRIV_CONTRACT_EVENT}
privilege asserted in its effective set.
-v Request verbose event descriptions.
OPERANDS
The following operands are supported:
contract-type Valid contract types are:
process Process contracts.
contract-id A valid contract id.
OUTPUT
The following list defines the column headings and the meanings of a
ctwatch report:
CTID The contract ID generating the event.
EVID The event ID.
CRIT Whether the event is informative, critical, or initiates an
exit negotiation. Values are info, crit, or neg, respec‐
tively.
ACK The event has been acknowledged. Values are yes or "no".
CTTYPE The contract type.
SUMMARY A type-specific summary of the event.

leges(5)NOTES
Ordering of events is only guaranteed within a single contract, or
within a single type when a type is specified.
ctwatch can only observe those events which are generated by contracts
owned or authored by processes with the same effective user ID as
ctwatch, unless the {PRIV_CONTRACT_OBSERVER} privilege is asserted in
its effective set.
