From 71ca2ffd565833fd203de59fbbf6f17ffe07f111 Mon Sep 17 00:00:00 2001 From: Jason Antman Date: Sun, 30 Nov 2025 11:47:00 -0500 Subject: [PATCH 1/4] Add users config file tracking with mtime, Prometheus metric, and Slack status MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This commit adds comprehensive tracking of the users configuration file to provide better visibility into user data freshness and system state. Changes: - Added file_mtime field to UsersConfig model that tracks the modification time of users.json on load and reload operations - Created _get_config_path() helper method to retrieve the config file path from environment or use default - Exposed user_config_file_mtime as a new Prometheus metric for monitoring - Updated Slack machine status response to include a header line showing: * Age of users config (human-readable format) * Number of configured users * Number of configured fobs - Updated admin.rst documentation with the new Prometheus metric Testing: - Updated existing UsersConfig tests to verify file_mtime is set correctly - Added new test_reload_updates_file_mtime() to ensure mtime updates on reload - Updated Prometheus metric tests to include and verify new metric - Updated Slack handler tests to verify new status header line format - All 156 tests passing with 99% code coverage The file_mtime tracking enables monitoring when user data was last updated, which is useful for detecting stale data and debugging synchronization issues with external systems like NeonOne CRM. 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- docs/source/admin.rst | 3 ++ src/dm_mac/models/users.py | 9 ++++++ src/dm_mac/slack_handler.py | 9 +++++- src/dm_mac/views/prometheus.py | 6 ++++ tests/models/test_users.py | 50 +++++++++++++++++++++++++++++++++- tests/test_slack_handler.py | 7 ++++- tests/views/test_prometheus.py | 23 ++++++++++++++-- 7 files changed, 102 insertions(+), 5 deletions(-) diff --git a/docs/source/admin.rst b/docs/source/admin.rst index 3a24c0e..fd76913 100644 --- a/docs/source/admin.rst +++ b/docs/source/admin.rst @@ -58,6 +58,9 @@ An example response from the metrics endpoint is: # HELP user_config_load_timestamp The timestamp when the users config was loaded # TYPE user_config_load_timestamp gauge user_config_load_timestamp 1.689477248e+09 + # HELP user_config_file_mtime The modification time of the users config file + # TYPE user_config_file_mtime gauge + user_config_file_mtime 1.689477248e+09 # HELP app_start_timestamp The timestamp when the server app started # TYPE app_start_timestamp gauge app_start_timestamp 1.689477248e+09 diff --git a/src/dm_mac/models/users.py b/src/dm_mac/models/users.py index 008066e..b6fe051 100644 --- a/src/dm_mac/models/users.py +++ b/src/dm_mac/models/users.py @@ -1,6 +1,7 @@ """Models for users and tools for loading users config.""" import logging +import os from time import time from typing import Any from typing import Dict @@ -127,6 +128,13 @@ def __init__(self) -> None: for fob in user.fob_codes: self.users_by_fob[fob] = user self.load_time: float = time() + self.file_mtime: float = os.path.getmtime(self._get_config_path()) + + def _get_config_path(self) -> str: + """Get the path to the users config file.""" + if "USERS_CONFIG" in os.environ: + return os.environ["USERS_CONFIG"] + return "users.json" def _load_and_validate_config(self) -> List[Dict[str, Any]]: """Load and validate the config file.""" @@ -211,4 +219,5 @@ def reload(self) -> Tuple[int, int, int]: added += 1 logger.info("Done reloading users config.") self.load_time = time() + self.file_mtime = os.path.getmtime(self._get_config_path()) return removed, updated, added diff --git a/src/dm_mac/slack_handler.py b/src/dm_mac/slack_handler.py index 82738ff..7ea7b0c 100644 --- a/src/dm_mac/slack_handler.py +++ b/src/dm_mac/slack_handler.py @@ -16,6 +16,7 @@ from dm_mac.models.machine import Machine from dm_mac.models.machine import MachinesConfig +from dm_mac.models.users import UsersConfig logger: logging.Logger = logging.getLogger(__name__) @@ -170,7 +171,13 @@ async def handle_command(self, msg: Message, say: AsyncSay) -> None: async def machine_status(self, say: AsyncSay) -> None: """Respond with machine status.""" -
