Command Reference for perfSONAR's pScheduler
Essential InformationpScheduler and this cheat sheet are a work in progress. |
Guide to Symbols | Something in development or used for development and debug purposes | | Required argument or parameter |
Basic Command StructureAll pScheduler commands follow the same format:
pscheduler COMMAND [ ARGUMENTS ]
An alias, psc is provided for convenience:
psc COMMAND [ ARGUMENTS ] |
Argument Typesduration | An ISO 8601 duration (e.g., PT1H30M or P3D). Months and years are not supported. | host | The DNS name or IP address of a host | number | A number, usually positive. | timestamp | An ISO 8601 timestamp (e.g., 2016-05-04T12:34:56-04:00) |
taskTells pScheduler to set up a task | Synopsis: | psc task TASK-OPTIONS TEST-TYPE TEST-OPTIONS
| General TASK-OPTIONS: | --export - Export JSON for the task to the standard output and don't submit it for scheduling.
| --format format - Output format for results. Valid formats are text, html, json and none. Default is text.
| --import file - Import JSON for the task from file.
| --quiet - Display nothing but results and errors.
| --reference json - Include the arbitrary blob of JSON json for the submitter's reference.
| --tool tool - Force the tool tool to be used for the test. Repeat to allow a list of tools, preferred in the order specified.
| --url - Print the URL for the task and exit.
| Scheduling TASK-OPTIONS: | --max-runs cardinal - Repeat the task up to the specified number of times. Requires --repeat.
| --randslip float - Randomize the start time by this fraction of the allowed slip. Must be in [0.0..1.0].
| --repeat duration - Amount of time between runs.
| --slip duration - Allow the start of any run to slip by the specified amount of time.
| --start timestamp - When the first run of the task should start.
| --until timestamp - Allow repeats to continue until the specified time. Requires --repeat.
|
watchThe watch command shows the results for runs of a task, identified by a URL, as they happen | | latency - One-Way Network Traversal Time This test is in development. |
rtt - Round Trip Time Between Hosts--count n - How many times the round-trip time should be tested
| --deadline duration - Deadline for all measurements to finish
| --dest host - The destination host for the test
| --flowlabel number - The flow label to be used on outgoing packets
| --[no-]hostnames - [Dis]able resolution of host names from IPs. Default is to resolve.
| --interval duration - Time to wait between packets sent
| --length number - Set the size of outgoing packets
| --source host - Source address or interface
| --timeout duration - How long to wait for each packet to return
| --tos number - Set the IP type of service on outgoing packets
| --ttl number - Set the time to live on outgoing packets
|
throughput - Available Bandwidth Between Hosts This test is in development. |
trace - Path Between Hosts--algorithm - Use a specific algorithm for the trace. Valid value is paris-traceroute.
| --[no-]as - [Dis]able lookup of autonomous system numbers and owner information.
| --dest-port number - Port where packets will be sent when the probe type is udp or tcp.
| --dest host - The far end of the trace
| --first-ttl number - Time to live on the first packet sent
| --[no-]fragment - [Dis]able fragmentation
| --hops number - Maximum number of hops (largest TTL)
| --[no-]hostnames - [Dis]able resolution of host names from IPs. Default is to resolve.
| --ip-version number - Set the version of the IP protocol to be used. Valid values are 4 and 6.
| --length number - Size of outgoing packets
| --probe-type t - Type of probes sent. Valid values are icmp, udp and tcp. Default is udp.
| --queries number - Number of queries per hop. Default is 1.
| --sendwait duration - Amount of time to wait between probes
| --source host - Source address or host name
| --tos number - IP type of service on outgoing packets
| --wait duration - Wait time for probes to be returned
|
idle - Do Nothing Useful--duration duration - How long the test should do nothing
| --host *host - The host which should be idle
| --parting-comment text - Text to be logged at the end of the idle period
| --starting-comment text - Text to be logged at the start of the idle period
|
This test is intended for use in development and troubleshooting pScheduler. simplestream - TCP Stream Between Hosts--dest host - Receiving end of the stream
| --dawdle duration - Maximum amount of time spent delaying before sending the test material
| --fail probability - Probability that the test will be forced to fail
| --test-material text - String to be sent. Defaults to a message containing a timestamp.
| --timeout duration - How long the receiving end should wait for the sending end before giving up
