9 | Venator is a application for recording, viewing, and filtering logs and spans
10 | from programs instrumented with the Rust tracing crate or using OpenTelemetry.
11 | It is purpose-built for rapid local development.
12 |
13 |
14 |
15 |
16 |
17 | ## Installation
18 |
19 | ### With Pre-built Binaries:
20 |
21 | Binaries are pre-built and available in the [releases page](https://github.com/kmdreko/venator/releases) for:
22 | - Windows (x64)
23 | - MacOS (Intel, Apple silicon)
24 |
25 | ### With Cargo:
26 |
27 | Compiling and installing `venator` from source with Cargo (requires Rust 1.76 or
28 | newer):
29 |
30 | ```
31 | cargo install venator-app
32 | ```
33 |
34 | ## Usage
35 |
36 | ### Using OpenTelemetry:
37 |
38 | Configure your program's OpenTelemetry SDK to export logs and traces to
39 | `127.0.0.1:8362` (Venator's default listening port) and to use `grpc` or
40 | `http/protobuf`.
41 |
42 | ### Using Rust Tracing:
43 |
44 | In your instrumented program:
45 |
46 | ```toml
47 | [dependencies]
48 | venator = "1.1.0"
49 | ```
50 |
51 | ```rust
52 | use venator::Venator;
53 |
54 | Venator::default().install();
55 | ```
56 |
57 | See the [documentation](https://docs.rs/venator/latest/venator/) for more.
58 |
59 | ## Features
60 |
61 | Events can be viewed narrowed by timespan and filtered by attributes, level, and
62 | other properties. The table of records can include columns of custom properties.
63 | The graph shows the counts by level at each bar.
64 |
65 |
66 |
67 |
68 |
69 | Spans can likewise be narrowed by timespan and filter. A detail pane can show
70 | all the properties of selected events and spans. The graph shows spans layered
71 | hierarchically.
72 |
73 |
74 |
75 |
76 |
77 | Traces can be viewed that show both events and spans within a single execution.

/docs/filter-syntax.md:
--------------------------------------------------------------------------------
1 | # Venator Filter Syntax
2 |
3 | The filter is composed of `property: value` predicates that an event or span
4 | must satisfy to be shown.
5 |
6 | Properties come in two kinds:
7 |
8 | - *inherent* properties start with `#` and correspond to values built-in to
9 | the instrumentation and reporting of events and spans. The available
10 | inherent properties are:
11 | - `#level`:
12 | - `#parent`:
13 | - `#trace`:
14 | - `#target`:
15 | - `#file`:
16 |
17 | - *attribute* properties start with `@` and are user-defined structured logging
18 | fields that can be provided on events and spans. Nested events and spans
19 | inheret the attributes of their parent span(s) and root unless overridden.
20 |
21 | Values can take a few different forms:
22 |
23 | - if the value matches `true` and `false` it will match boolean values as well
24 | as literal strings with those exact characters.
25 | - if the value can be parsed as an integer like `42` it will match integer and
26 | float values that equal the value as well as literal strings with those
27 | exact characters.
28 | - if the value can be parsed as a float like `6.09` or `-2.44e9` it will match
29 | float values that equal it as well as literal strings with those exact
30 | characters.
31 | - if the value starts and ends with `/` like `/[0-9a-f]{32}/` it will be parsed
32 | as a regex and will match string values satifying that regex.
33 | - if the value contains a `*` it will be interpretted as a wildcard (unless
34 | escaped like `\*`) and will match strings where `*` can satisfy any number
35 | of characters.
36 | - if the value starts and ends with `"` then it is interpretted literally
37 | (except `*`s still mean a wildcard) and will not try to parse other symbols
38 |
39 | Values can also have operators applied to them:
40 |
41 | - `!value` will match values that do __not__ satisfy that value (can have other
42 | operators as well)
43 | - `value` will match values greater than that value (lexicographical comparison
46 | for strings; numerical comparison for integers, floats, and booleans)
47 | - `<=value` will match values less than or equal to that value (lexicographical
48 | comparison for strings; numerical comparison for integers, floats, and
49 | booleans)
50 | - `>=value` will match values greater than or equal to that value (lexicographical
51 | comparison for strings; numerical comparison for integers, floats, and
52 | booleans)
53 | - `(value1 AND value2 ...)` will match values only if all are satisfied
54 | - `(value1 OR value2 ...)` will match values if any are satisfied
55 |
56 |
57 | ## FAQ
58 |
59 |
60 | ### How to filter for a value with spaces?
61 |
62 | You can surround a value with quotes `"` to include characters that would
63 | otherwise be misinterpretted - like spaces, `:`, `!`, and other operators:
64 |
65 | ```
66 | @name: "John Titor" @category: "decor:lighting"
67 | ```
68 |
69 | Note that quotes may be automatically removed when its not warranted and may
70 | be automatically added if a value was able to be parsed but includes special
71 | characters out of an abundance of clarity.
72 |
73 | This goes for attributes as well:
74 |
75 | ```
76 | @"first name": John @"category:name": lighting
77 | ```
78 |
79 |
80 | ### How to exclude a value?
81 |
82 | You can use `!` to negate a filter which will work on values:
83 |
84 | ```
85 | @name: !John
86 | ```
87 |
88 | It is worth noting however that the results will also include events or spans
89 | that do not have that property. To only get results that have the property
90 | set but are *not* a particular value, you can combine it with an "exists"
91 | filter:
92 |
93 | ```
94 | @name: (* AND !John)
95 | ```
96 |
97 |
98 | ### How to filter for a property that exists?
99 |
100 | A wildcard will typically only filter for values that are strings, however a
101 | bare `*` will include any value, so it can serve as an "exists" filter:
102 |
103 | ```
104 | @name: *
105 | ```
106 |
107 |
108 | ### How to filter for a range?
109 |
110 | The best way is to use an `AND` group with `>`/`>=` and `<`/`<=` comparison
111 | operators:
112 |
113 | ```
114 | #duration: (>1s AND <10s)
115 | ```
116 |
117 |
118 | ### How to filter for value that starts or ends with something?
119 |
120 | You can use wildcards at the end or beginning of a string value to get "starts
121 | with" or "ends with" behavior:
122 |
123 | ```
124 | @name: "John *" @message: "* items were found"
125 | ```
126 |
127 |
128 | ### How to filter for value in different properties?
129 |
130 | You can use an `(... OR ...)` grouping around property-value pairs to find
131 | entities that may satisfy one predicate or another:
132 |
133 | ```
134 | (@name: John OR @legacy_name: John)
135 | ```
136 |
137 |
138 | ### How to filter for a specific type of value?
139 |
140 | Not supported currently.

/docs/interface.md:
--------------------------------------------------------------------------------
1 | # Venator Interface
2 |
3 | The user interface is split into three meta regions:
4 | - the tab bar
5 | - the main screen
6 | - the status bar
7 |
8 |
9 | ## Tab Bar
10 |
11 | The tabs should be self-explanatory but I'll explain regardless. The app can
12 | have multiple "screens" open simulaneouosly; the most lit one is what is being
13 | shown and the unlit ones are backgrounded. You can switch to a tab by clicking
14 | on it. You can open a new tab by clicking one of the buttons on the right (one
15 | for an events screen, one for a spans screen) or by using the shortcut `CTRL+T`.
16 | You can close a tab by clicking on `X` when its active, or by middle-clicking.
17 | Hovering over a tab will show the screen type and full filter. More options are
18 | available via `View` in the menu and right-clicking a tab.
19 |
20 |
21 | ## Status Bar
22 |
23 | The status bar at the bottom of the screen shows information of the application
24 | overall.
25 |
26 | The bottom left shows the database file that is open (or the "default dataset"
27 | if launched by default) as well as if it is listening for connections and if so
28 | what address and port.
29 |
30 | The bottom right shows the running metrics. The first metric is the bytes per
31 | second being received from established connections. The next metric shows the
32 | number of connections currently established. The last metric shows the load on
33 | the underlying engine that is handling incomming data and responding to queries.
34 |
35 |
36 | ## Main Screen
37 |
38 | The main screen is where you can view events, spans, and other entities based on
39 | timeframe and filter. It is composed of a few key components:
40 | - the time controls
41 | - the filter input
42 | - the graph
43 | - the table
44 | - the details panel (collapsable)
45 |
46 |
47 | ### Time Controls
48 |
49 | These controls affect the timeframe that affects the graph and table results of
50 | the screen. It is split between the starting point and the duration of the time
51 | frame with an additional button for listening to live events.
52 |
53 | The starting point controls shows the currently set starting point and has
54 | buttons for shifting the starting point before or after in time. The main field
55 | can also be edited manually to set a specific time.
56 |
57 | The duration controls shows the currently set duration and has buttons for
58 | reducing or expanding the duration. The main field can also be edited manually
59 | to set a specific duration.
60 |
61 |
62 | ### Filter Input
63 |
64 | The filter input is where you can specify `property: value` predicates for
65 | narrowing down the events, spans, etc that are being shown. See [filter syntax](./filter-syntax.md)
66 | for details.
67 |
68 | An empty event or span screen will include a permanent `#level` filter for only
69 | showing entities at or above the specified log level. You can also hover and
70 | scroll on this predicate to increase or decrease the level.
71 |
72 | When editing the filter, any non-permanent predicates are undecorated and shown
73 | as a single text input. When hitting `Enter` or clicking off, the filter will be
74 | parsed and applied to the graph and table results. The predicates will be
75 | decorated based on their type (white for attributes, gray for inherent fields).
76 | The predicates will be highlighted in red if the value was invalid or the whole
77 | input will be highlighted red if there was a syntax error that meant the filter
78 | couldn't be properly split into predicates. Individual predicates can be right-
79 | clicked to copy or remove, or middle-clicked to remove them.
80 |
81 | Options in the table or details panel can add predicates to the filter.
82 |
83 |
84 | ### Graph
85 |
86 | The graph can take a few different forms based on the type of main screen. For
87 | events it will show bars of aggregated counts by log level. For spans it will
88 | show them individually spread across their timeframe stacked on top of eachother
89 | (up to 10 high). For traces it will show all spans and events stacked on top of
90 | eachother (squished to accomodate them all).
91 |
92 | Hovering your cursor over the graph will show the hovered timestamp in the top.
93 | Clicking and dragging will highlight a timeframe and zoom to it when released.
94 | You can also scroll on the graph to zoom in and out. Middle-click dragging will
95 | allow you to pan the timeframe left and right.
96 |
97 |
98 | ### Table
99 |
100 | The table shows the actual events or spans being queried by the filter and
101 | timeframe. By default it will show columns for the level, when it occurred
102 | (`#timestamp` for events, `#created_at` for spans) and a default column
103 | (`@message` for events, `#name` for spans). The timing column also includes a
104 | toggle for controlling the sort order.
105 |
106 | Each of the non-fixed columns have a `+` button in the header to create a new
107 | column. The column header can be edited to change the property which uses the
108 | same `#` and `@` syntax as the filter. You can also right-click on the header to
109 | access various options or middle-click to remove it.
110 |
111 | The table cells contain the value for the entity and property of the row and
112 | column. If a value does not exist, it will show as `---`. Clicking on a row will
113 | show or hide the details panel for that entity. You can also right-click the
114 | cell to access various options for that value or property.
115 |
116 |
117 | ### Details Panel
118 |
119 | This panel opens alongside the table and shows all information about the entity
120 | selected. The top of the panel shows the inherent properties along with a
121 | `#stack` property that can be expanded or collapsed on-click to show parent
122 | spans.
123 |
124 | The highlighted section shows the primary data for the entity (`@message` for
125 | events and `#name` for spans).
126 |
127 | The bottom shows all the attributes and their values. The far left icon will
128 | indicate where that value came from (a missing icon means it is directly on the
129 | entity, a span icon means it came from a parent span, and a resource icon means
130 | it was provided by the root resource). You can hover over this icon for details
131 | or the right-click will include a `copy * id` option when available. The
132 | right-click menu shows many options for adding to the filter or even adding a
133 | column to the table. An attribute value that is too long will be cut off, but
134 | you can toggle the `-` after the attribute name to expand it.
