JSON Metrics

Routinator’s monitoring service provides comprehensive metrics in JSON format /api/v1/status endpoint. Here you can find an overview of all metrics and their meaning.

The JSON metrics consists of an object with the following members:

version

The version of Routinator.

serial

The current serial number for data served to RTR clients.

now

The date and time in UTC when this report was created.

lastUpdateStart

The date and time in UTC when the last validation run started.

lastUpdateDone

The date and time in UTC when the last validation run completed.

lastUpdateDuration

The duration of the last validation run in seconds.

tals

Metrics for each configured trust anchor. In most cases these will be the five Regional Internet Registries, but will include the trust anchors of any configured testbeds as well.

Each element of this object contains a publication metrics value as described below.

repositories

Metrics for each repository encountered during validation. Note that the data given here relates to the repository content used during validation. If the repository failed to update, then these numbers are from the stored old data.

Each element of this object contains a publication metrics value as described below. In addition, there is a member type that describes whether the repository is an RRDP or rsync repository.

vrpsAddedLocally

The number of VRPs added to the final data set from local exceptions.

rsync

Metrics for updates via rsync.

This is an object with one element for each repository that was updated via rsync during the last validation run. Each element contains an rsync update metrics value as described below.

rrdp

Metrics for updates via RRDP.

This is an object with one element for each repository that was updated via rsync during the last validation run. Each element contains an RRDP update metrics value as described below.

rtr

Metrics for the built-in RTR server. See RTR metrics below.

http

Metrics for the built-in HTTP server. See HTTP metrics below.

Publication Metrics

Publication metrics are provided both for all trust anchors and for each RPKI repository. They contain the following information:

vrpsTotal

The total number of VRPs found to be present and valid.

vrpsUnsafe

The number of VRPs that are considered unsafe. Depending on configuration, these may be included in the final set or dropped from it.

vrpsLocallyFiltered

The number of VRPs that are filtered as the result of a local exception.

vrpsDuplicate

The number of duplicate VRPs resulting from ROAs containing the same authorisation.

Note that if a VRP appears in multiple trust anchors or repositories, which occurrence is considered the duplicate depends on the order of processing which may change between validation runs. Thus, this number may change unexpectedly.

vrpsFinal

The number of VRPs that are contributed by this trust anchor or repository to the final set provided to your routers. This is the total number of VRPs, minus the ones that are locally filtered, duplicate, and, if configured to be dropped, unsafe.

validPublicationPoints

The number of valid publication points.

rejectedPublicationPoints

The number of rejected publication points.

A publication point is rejected if its manifest is invalid or if any objects listed on the manifest are missing or have a different content hash.

validManifests

The number of valid manifests.

invalidManifests

The number of invalid manifests.

A manifest is invalid if it is not correctly encoded, has expired or is not correctly signed by the issuing CA.

staleManifests

The number of stale manifests.

A manifest is stale if the current time is past the time an update to the manifest should have been issued. Whether a stale manifest is valid or invalid depends on configuration. By default it is considered invalid.

missingManifests

The number of missing manifests.

validCRLs

The number of valid certificate revocation lists.

invalidCRLs

The number of invalid certificate revocation lists.

A CRL is invalid if it is not correctly encoded or is not correctly signed by the issuing CA.

staleCRLs

The number of stale certificate revocation lists.

A CRL is stale if the current time is past the time an update should have been issued. Whether a stale CRL is valid or invalid depends on configuration. By default it is considered invalid.

strayCRLs

The number of stray certificate revocation lists.

Each CA should only issue one CRL. This CRL should both be listed on the manifest and used by the manifest’s certificate itself. Any manifest listed on the manifest that is not also the manifest’s own CRL is considered a stray.

validCACerts

The number of Certificate Authority (CA) certificates found to be present and valid.

validEECerts

The number of End Entity (EE) certificates found to be present and valid.

This only refers to such certificates included as stand-alone files which are BGPsec router certificates.

invalidCerts

The number of invalid stand-alone certificates, either CA or EE certificates.

validROAs

The number of valid Route Origin Attestations

invalidROAs

The number of invalid Route Origin Attestations.

validGBRs

The number of valid Ghostbusters Records.

Note that currently the content of a Ghostbuster Record is not checked.

InvalidGBRs

The number of invalid Ghostbusters Records.

otherObjects

The number of objects found that are not certificates (.cer), Certificate Revocation Lists (.crl), manifests (.mft), ROAs (.roa), or Ghostbuster Records (.gbr).

Rsync Update Metrics

For each repository updated via rsync the following values are given.

status: The status code returned by the rsync process. A value of 0 means the process has finished successfully. The meaning of other values depends on the rsync client used. Please refer to its documentation for further details.
duration: The duration the rsync process was running in seconds.

RRDP Update Metrics

For each repository updated via RRDP the following values are given.

status

The overall status of the update. This will be 200 if the updated succeeded, 304 if no update was necessary because the data was already current, and any other value for a failed update. If the value is -1, it was not possible to reach the HTTPS server at all.

notifyStatus

The status of retrieving the notification file. This is the first step of an RRDP update. A value of 200 indicates that the file was successfully retrieved. A value of 304 indicates that the file hasn’t changed since last update and no actual update is necessary. Any other value represents an error.

payloadStatus

The status of retrieving the actual payload. This is the second step of an RRDP update and may either represent a single HTTPS request for the snapshot file or a series of HTTPS request for the sequence of delta files necessary to update from the last known state.

A value of 0 means that no payload retrieval was necessary. A value of 200 means that the update was successful. Any other value indicates an error. In case of a sequence of delta updates, this error may have been preceded by one or more successful requests.

duration

The overall duration of the RRDP update in seconds.

serial

The serial number stated by the RRDP server for the current data set. With each update the serial number is increased by one.

session

The identifier of the current session of the RRDP server. Serial numbers are only valid within the same session. If the server needs to restart its sequence for whatever reason, it needs to choose a new session ID and all data will have to be updated through a snapshot.

delta

Whether data was updated via a sequence of deltas (true) or a full snapshot had to be retrieved (false).

snapshotReason

If this is not null, it provides a reason why a snapshot was used instead of a delta as a short explanatory string.

RTR Server Metrics

A number of metrics are provided describing the state of the included RTR server. These metrics are available whether the RTR server is actually enabled or not.

currentConnections: The number of currently open RTR connections.
bytesRead: The total number of bytes read from RTR connections. In other words, describes how much data has been sent by clients.
bytesWritten: The total number of bytes written to RTR connections. In other words, describes how much data has been sent to clients.

If rtr-client-metrics are enabled via configuration or command line, an additional object clients will appear that list the IP addresses of clients seen by the RTR server providing the following information for them.

connections: The number of currently open connections from that address. The number should normally be 0 or 1 but can be higher if the address is the public side of a NAT.
updated: Contains the time of the last successful update by the client.
lastReset: Contains the time of the last successful cache reset by the client.
resetQueries: Contains the number of reset queries by the client.
serialQueries: Contains the number of serial queries by the client.
serial: The highest serial of the data provided to a client from that address. This can be used to determine when the client has last updated.
read and written: Bytes read from and written to clients from that address.

HTTP Server Metrics

A number of metrics are provided describing the state of the included HTTP server.

totalConnections: The total number of connections made with the HTTP server.
currentConnections: The number of currently open connections. This should at least be 1 as there is a connection open when requesting the JSON metrics.
requests: The total number of requests received and answered by the HTTP server.
bytesRead and bytesWritten: The number of bytes read from and written to HTTP clients.
