bigfix-remote-session-relevance

Evaluate BigFix session relevance through the root server REST API, BigFix Explorer, the Web Reports SOAP API, or BigFix SaaS, against every configured deployment at once, and get the same result back whichever one answered.

uvx bigfix-remote-session-relevance "number of bes computers"

The session-relevance counterpart to bigfix-remote-client-relevance.

What it does

• One result type. REST (JSON), Explorer (JSON) and Web Reports (SOAP XML) all return a SessionRelevanceResult with native answers (int, bool, str, tuples), the type string, plurality and evaluation time. Callers never see the wire format; result.raw has it when asked for.
• Consistent errors. Relevance errors, bad credentials, unreachable hosts and login pages come back as results with error.kind set. The kind and message are the same on every backend.
• Many servers. Any number of root servers, Explorers and Web Reports servers. Connections to the same deployment are recognized automatically (sha256 of gather url of bes license), and by default each deployment is queried once, concurrently, with failover between its connections.
• Trust on first use for self-signed BigFix certificates: confirm a certificate once and it is pinned. A changed certificate is a hard error.
• Auth: Basic or bearer token (11.0.6+ "API key") for REST and Explorer, mTLS client certificates for Explorer, username/password for Web Reports. BigFix SaaS signs in with email/password (TOTP prompted when required).
• Explorer extras (keys, filters) are additive and opt in.
• Async first, with an equally capable sync API. Pure-Python dependencies only.

Setup

uvx bigfix-remote-session-relevance --setup

The wizard asks for a host, username and password, probes the REST API (52311), Explorer (9383) and Web Reports (443/8083/80/8080), pins certificates after showing their fingerprints, and writes ~/.bigfix/.remote_session_connections.toml (mode 0600).

For BigFix SaaS, enter login.bigfix.com (or eulogin.bigfix.com) as the host, then your email and password; a TOTP code is asked for only if your account uses MFA. Setup signs in once and saves one connection per BigFix server your account can reach. A rejected sign-in is never retried or saved: BigFix SaaS locks an account after 100 failed logins. See remote_session_connections.example.toml for every option. server is normally just a host name: https:// and the backend's default port are assumed.

Passwords can live in the file, or better, in environment variables named by password_env.

CLI

bigfix-remote-session-relevance "names of bes sites"            # one answer per line
bigfix-remote-session-relevance --json "ids of bes computers"   # list of result objects
bigfix-remote-session-relevance --all "now"                     # every connection, not one per deployment (= -all, --all-connections)
bigfix-remote-session-relevance --backend webreports --raw "1"  # raw server response
bigfix-remote-session-relevance --keys "id name" \
    "(id of it, name of it) of bes computers"                  # Explorer extras
echo "number of bes fixlets" | bigfix-remote-session-relevance -
bigfix-remote-session-relevance --show-config                   # connections, no secrets
bigfix-remote-session-relevance --show-certs | --trust-cert NAME | --forget-cert HOST:PORT

Answers go to stdout; errors and -v metadata go to stderr.

Results stream in as each deployment answers (completion order), so a slow or unreachable server no longer holds up the ones that already finished. Plain text and --raw stream; --json is one document, so it prints once everything is in. Exit codes are always decided after the full fan-out.

When several results come back, plain text ends with a summary that collapses identical answers, most common first:

== summary: 3 results, 2 distinct answers
2× 1234
    prod-root (rest), dr-root (rest)
1× 87
    lab-wr (webreports)

Results are grouped by answers, answer type and error (not timing, backend or server), and identical errors collapse too. The summary only appears when it actually collapses something.

Library

from bigfix_remote_session_relevance import evaluate_session_relevance

for result in evaluate_session_relevance("(id of it, name of it) of bes computers"):
    if result.ok:
        print(result.connection, result.answers)  # ((1, 'host-a'), ...)
    else:
        print(result.connection, result.error.kind, result.error.message)

from bigfix_remote_session_relevance import AsyncSessionRelevanceClient

async with AsyncSessionRelevanceClient() as client:  # default config
    results = await client.evaluate("number of bes computers")
    results.raise_for_error()  # opt into exceptions

    async for result in client.evaluate_stream("number of bes computers"):
        print(result.connection, result.answers)  # as each deployment answers
    keyed = await client.evaluate_explorer(
        "(id of it, name of it) of bes computers", keys="id name"
    )

SessionRelevanceClient has the same methods, synchronously, and works even inside a running event loop. Single backends (RestBackend, ExplorerBackend, WebReportsBackend) can be used directly too.
