from line 853
853853* `duration_ms`: Connection attempt duration in milliseconds
854854* `error_code`: Error code when the connection failed
855855* `is_plugin`: `true` when the server is provided by a plugin, `false` otherwise
856* `plugin_id_hash` (when `is_plugin` is `true`): Stable hash of the plugin name and marketplace, for grouping events by plugin without exposing the name
856* `plugin_id_hash` (when `is_plugin` is `true`): Stable hash of the plugin name and marketplace, for grouping events by plugin without exposing the name. Claude Code computes it as described under the [plugin loaded event](#plugin-loaded-event)
857857* `plugin.name` (when `is_plugin` is `true`): Name of the plugin that provides the server. For third-party plugins this is the literal string `"third-party"` unless `OTEL_LOG_TOOL_DETAILS=1`; this protects third-party plugin names from appearing in logs by default. Plugins from official Anthropic sources are always identified by name. The `plugin_id_hash` and `plugin.name` attributes flow to your own monitoring backend and are not sent to Anthropic
858858* `server_name` (when `OTEL_LOG_TOOL_DETAILS=1`): Configured server name
859859* `error` (when `OTEL_LOG_TOOL_DETAILS=1`): Full error message when the connection failed
from line 906
906906* `plugin.name`: name of the plugin. For plugins outside the official marketplace and built-in bundle the value is `"third-party"` unless `OTEL_LOG_TOOL_DETAILS=1`
907907* `marketplace.name`: marketplace the plugin was installed from, when known. Redacted to `"third-party"` under the same condition as `plugin.name`
908908* `plugin.version`: version from the plugin manifest. Included only when the name is not redacted and the manifest declares a version
909* `plugin.scope`: provenance category for the plugin: `"official"`, `"org"`, `"user-local"`, or `"default-bundle"`
910* `enabled_via`: how the plugin came to be enabled: `"default-enable"`, `"org-policy"`, `"seed-mount"`, or `"user-install"`
911* `plugin_id_hash`: deterministic hash of the plugin name and marketplace, sent only to your configured exporter. Lets you count how many distinct third-party plugins are loaded across your fleet without recording their names
909* `plugin.scope`: provenance category for the plugin: `"official"`, `"community"`, `"org"`, `"user-local"`, or `"default-bundle"`
910* `enabled_via`: how the plugin came to be enabled: `"default-enable"`, `"org-policy"`, `"admin-install"`, `"seed-mount"`, or `"user-install"`. The `"admin-install"` value means the plugin is set to required or auto-install for your organization in [**Organization settings > Plugins**](https://claude.ai/admin-settings/plugins). Before v2.1.246, Claude Code reported these plugins as `"user-install"` or `"seed-mount"`
911* `plugin_id_hash`: deterministic hash of the plugin name and marketplace, sent only to your configured exporter. Lets you count the distinct third-party plugins loaded across your fleet without recording their names. For [plugins synced from claude.ai](/docs/en/plugins-reference#synced-plugins), Claude Code hashes the plugin name with the marketplace name that claude.ai reports for the plugin, or with `synced` otherwise. Before v2.1.246, Claude Code didn't use the marketplace name claude.ai reports in the hash
912912* `has_hooks`: whether the plugin contributes hooks
913913* `has_mcp`: whether the plugin contributes MCP servers
914914* `host_owned_mcp`: `true` when the SDK host manages this plugin's MCP connections and Claude Code skipped reading the plugin's MCP server configuration, `false` otherwise. Requires Claude Code v2.1.172 or later
from line 988
988988* `safe_mode`: `"true"` when the session was started with [`--safe-mode`](/docs/en/cli-reference), `"false"` otherwise. Requires Claude Code v2.1.169 or later
989989* `hook_matcher` (when `OTEL_LOG_TOOL_DETAILS=1`): the matcher string from the hook configuration, when one is set
990990* `plugin.name` (when `hook_source` is `"pluginHook"`): name of the contributing plugin. For plugins outside the official marketplace and built-in bundle the value is `"third-party"` unless `OTEL_LOG_TOOL_DETAILS=1`
991* `plugin_id_hash` (when `hook_source` is `"pluginHook"`): deterministic hash of the plugin name and marketplace, sent only to your configured exporter. Lets you count distinct contributing plugins without recording their names
991* `plugin_id_hash` (when `hook_source` is `"pluginHook"`): deterministic hash of the plugin name and marketplace, sent only to your configured exporter. Lets you count distinct contributing plugins without recording their names. Claude Code computes it as described under the [plugin loaded event](#plugin-loaded-event)
