ctstat(1) User Commands ctstat(1)NAMEctstat - display active system contracts
SYNOPSIS
/usr/bin/ctstat [-a] [-i contractid...] [-t type...] [-v]
[interval [count]]
DESCRIPTION
The ctstat utility allows a user to observe the contracts active on a
system.
Unless you specify the -i or -t option, ctstat displays statistics on
all contracts in the system.
OPTIONS
The following options are supported:
-a Display all contracts regardless of state. By
default, only those contracts which are in the
owned, inherited, or orphan states are displayed.
-i contractid... Request status on the specified contracts, identi‐
fied by their numeric contract identifier (con‐
tract_id).
This option accepts lists as arguments . Items in
the list can be separated by commas, or enclosed in
quotes and separated by commas or spaces.
-t type... Request status on contracts of the specified type
(type).
This option accepts lists as arguments. Items in
the list can be separated by commas, or enclosed in
quotes and separated by commas or spaces.
The following types are supported:
process Process contracts
-v Verbose output.
OPERANDS
The following operands are supported:
interval Report once each interval seconds.
count Print only count reports.
OUTPUT
The following list defines the column headings and the meanings of a
ctstat report:
CTID The contract ID of the contract.
ZONEID The zone ID of the contract's creator.
TYPE The contract type.
STATE The state of the contract:
owned Contract is owned by a process.
inherited The contract owner has exited abnormally and the
contract has been inherited by the owner's
process contract.
orphan The contract owner has abandoned the contract,
the contract owner exited abnormally and the
contract was not inherited by the owner's
process contract, or the process contract which
had inherited the contract was abandoned by its
owner.
dead The contract is no longer active. It is removed
from the system automatically when all refer‐
ences to it (open file descriptors, contract
templates, and events) have been released.
HOLDER If the contract is in the owned state, the pid of the process
that owns the contract. If the contract is in the inherited
state, the id of the regent process contract.
EVENTS The number of unacknowledged critical events pending.
QTIME The time until quantum ends, or - if no negotiation is in
progress.
NTIME The time until negotiation ends, or - if no negotiation is in
progress.
