| 4 | |
| 5 | ### Added |
| 6 | |

| 10 | |
| 11 | - `promql/comparison` only applies to alerts, so it was renamed to |
| 12 | `alerts/comparison`. |
| 13 | - Online documentation hosted at [cloudflare.github.io/pint](https://cloudflare.github.io/pint/) |
| 14 | was reworked. |
| 15 | - `alerts/count` check will now retry range queries with shorter time window |
| 16 | on `found duplicate series for the match group ...` errors from Prometheus. |
| 17 | |

| 24 | |
| 25 | ## v0.11.0 |
| 26 | |
| 27 | ### Added |
| 28 | |
| 29 | - Added `promql/regexp` check that will warn about unnecessary regexp matchers. |
| 30 | - Added `pint_prometheus_queries_total` and `pint_prometheus_query_errors_total` |

| 51 | ### Changed |
| 52 | |
| 53 | - Removed `lines` label from `pint_problem` metric exported when running `pint watch`. |
| 54 | - Multiple `match` and `ignore` blocks can now be specified per each `rule`. |

| 77 | |
| 78 | - Added new `promql/fragile` check. |
| 79 | - BitBucket reports will now include a link to documentation. |
| 80 | |
| 81 | ## v0.7.3 |
| 82 | |
| 83 | ### Added |

| 90 | |
| 91 | - More aggressive range reduction for `query processing would load too many samples into memory` |
| 92 | errors when sending range queries to Prometheus servers. |
| 93 | |
| 94 | ## v0.7.1 |
| 95 | |
| 96 | ### Added |
| 97 | |
| 98 | - Added `command` filter to `match` / `ignore` blocks. This allows to include |
| 99 | skip some checks when (for example) running `pint watch` but include them |
| 100 | in `pint lint` run. |
| 101 | |
| 102 | ## v0.7.0 |
| 103 | |
| 104 | ### Added |
| 105 | |
| 106 | - Cache each Prometheus server responses to minimize the number of API calls. |
| 107 | - `pint watch` will start a daemon that will continuously check all matching rules |
| 108 | and expose metrics describing all discovered problems. |
| 109 | |
| 110 | ### Changed |
| 111 | |
| 112 | - `alerts/annotation` and `rule/label` now include `required` flag value in |
| 113 | `# pint disable ...` comments. |
| 114 | Rename `# pint disable alerts/annotation($name)` to |
| 115 | `# pint disable alerts/annotation($name:$required)` and |
| 116 | `# pint disable rule/label($name)` to `# pint disable rule/label($name:$required)`. |
| 117 | - `--offline` and `--disabled` flags are now global, use `pint --offline lint` instead |
| 118 | of `pint lint --offline`. |
| 119 | |
| 120 | ### Fixed |
| 121 | |
| 122 | - `promql/rate`, `query/series` and `promql/vector_matching` checks were not enabled |
| 123 | for all defined `prometheus {}` blocks unless there was at least one `rule {}` block. |
| 124 | - `annotation` based `match` blocks didn't work correctly. |
| 125 | |
| 126 | ## v0.6.6 |
| 127 | |
| 128 | ### Fixed |
| 129 | |
| 130 | - File renames were not handled correctly when running `git ci` on branches with |
| 131 | multiple commits. |
| 132 | |
| 133 | ## v0.6.5 |
| 134 | |
| 135 | ### Added |
| 136 | |
| 137 | - Allow disabling `query/series` check for individual series using |
| 138 | `# pint disable query/series(my_metric_name)` comments. |
| 139 | |
| 140 | ## v0.6.4 |
| 141 | |
| 142 | ### Fixed |
| 143 | |
| 144 | - Fixed docker builds. |
| 145 | |
| 146 | ## v0.6.3 |
| 147 | |
| 148 | ### Fixed |
| 149 | |
| 150 | - `aggregate` check didn't report stripping required labels on queries |
| 151 | using aggregation with no grouping labels (`sum(foo)`). |
| 152 | - `aggregate` check didn't test for name and label matches on alert rules. |
| 153 | |
| 154 | ## v0.6.2 |
| 155 | |
| 156 | ### Changed |
| 157 | |
| 158 | - `template` check will now include alert query line numbers when reporting issues. |
| 159 | |
| 160 | ## v0.6.1 |
| 161 | |
| 162 | ### Fixed |
| 163 | |
| 164 | - Labels returned by `absent()` are only from equal match types (`absent(foo="bar")`, |
| 165 | not `absent(foo=~"bar.+")` but `alerts/template` didn't test for match type when |
| 166 | checking for labels sourced from `absent()` queries. |
| 167 | |
| 168 | ## v0.6.0 |
| 169 | |
| 170 | ### Changed |
| 171 | |
| 172 | - `aggregate` check was refactored and uses to run a single test for both |
| 173 | `by` and `without` conditions. As a result this check might now find issues |
| 174 | previously undetected. |
| 175 | Check suppression comments will need to be migrated: |
| 176 | * `# pint disable promql/by` becomes `# pint disable promql/aggregate` |
| 177 | * `# pint disable promql/without` becomes `# pint disable promql/aggregate` |
| 178 | * `# pint ignore promql/by` becomes `# pint ignore promql/aggregate` |
| 179 | * `# pint ignore promql/without` becomes `# pint ignore promql/aggregate` |
| 180 | |
| 181 | ## v0.5.3 |
| 182 | |
| 183 | ### Fixed |
| 184 | |
| 185 | - Fixed false positive reports in `aggregate` check. |
| 186 | |
| 187 | ## v0.5.2 |
| 188 | |
| 189 | ### Added |
| 190 | |
| 191 | - `--no-color` flag for disabling output colouring. |
| 192 | |
| 193 | ### Fixed |
| 194 | |
| 195 | - Fixed duplicated warnings when multiple `rule {...}` blocks where configured. |
| 196 | |
| 197 | ## v0.5.1 |
| 198 | |
| 199 | ### Fixed |
| 200 | |
| 201 | - Specifying multiple `# pint disable ...` comments on a single rule would only apply |
| 202 | last comment. This now works correctly and all comments will be applied. |
| 203 | |
| 204 | ## v0.5.0 |
| 205 | |
| 206 | ### Added |
| 207 | |
| 208 | - Added `alerts/for` check that will look for invalid `for` values in alerting rules. |
| 209 | This check is enabled by default. |
| 210 | |
| 211 | ### Changed |
| 212 | |
| 213 | - `comparison` check is now enabled by default and require no configuration. |
| 214 | Remove `comparison{ ... }` blocks from pint config file when upgrading. |
| 215 | - `template` check is now enabled by default and require no configuration. |
| 216 | Remove `template{ ... }` blocks from pint config file when upgrading. |
| 217 | - `rate` check is now enabled by default for all configured Prometheus servers. |
| 218 | Remove `rate{ ... }` blocks from pint config file when upgrading. |
| 219 | - `series` check is now enabled by default for all configured Prometheus servers. |
| 220 | Remove `series{ ... }` blocks from pint config file when upgrading. |
| 221 | - `vector_matching` check is now enabled by default for all configured Prometheus servers. |
| 222 | Remove `vector_matching{ ... }` blocks from pint config file when upgrading. |
| 223 | |
| 224 | ## v0.4.4 |
| 225 | |
| 226 | ### Added |
| 227 | |
| 228 | - Support `parseDuration` function in alert templates added in Prometheus 2.32.0 |
| 229 | |
| 230 | ## v0.4.3 |
| 231 | |
| 232 | ### Fixed |
| 233 | |
| 234 | - Fixed `series` check handling of queries with `{__name__="foo"}` selectors. |
| 235 | |
| 236 | ## v0.4.2 |
| 237 | |
| 238 | ### Fixed |
| 239 | |
| 240 | - Fixed `template` check handling of `absent` calls on aggregated metrics, like |
| 241 | `absent(sum(nonexistent{job="myjob"}))`. |
| 242 | |
| 243 | ## v0.4.1 |
| 244 | |
| 245 | ### Added |
| 246 | |
| 247 | - `template` check will now warn if any template is referencing a label that is not passed to |
| 248 | `absent()`. |
| 249 | Example: |
| 250 | |
| 251 | {% raw %} |
| 252 | ```yaml |
| 253 | - alert: Foo |
| 254 | expr: absent(foo{env="prod"}) |
| 255 | annotations: |
| 256 | summary: 'foo metric is missing for job {{ $labels.job }}' |
| 257 | ``` |
| 258 | {% endraw %} |
| 259 | |
| 260 | Would generate a warning since `absent()` can only return labels that are explicitly |
| 261 | passed to it and the above call only passes `env` label. |
| 262 | This can be fixed by updating the query to `absent(foo{env="prod", job="bar"})`. |
| 263 | |
| 264 | ## v0.4.0 |
| 265 | |
| 266 | ### Added |
| 267 | |
| 268 | - `comparison` check will now warn when alert query uses |
| 269 | [bool](https://prometheus.io/docs/prometheus/latest/querying/operators/#comparison-binary-operators) |
| 270 | modifier after condition, which can cause alert to always fire. |
| 271 | Example: |
| 272 | |
| 273 | ```yaml |
| 274 | - alert: Foo |
| 275 | expr: rate(error_count[5m]) > bool 5 |
| 276 | ``` |
| 277 | |
| 278 | Having `bool` as part of `> 5` condition means that the query will return value `1` when condition |
| 279 | is met, and `0` when it's not. Rather than returning value of `rate(error_count[5m])` only when |
| 280 | that value is `> 5`. Since all results of an alerting rule `expr` are considered alerts such alert |
| 281 | rule could always fire, regardless of the value returned by `rate(error_count[5m])`. |
| 282 | |
| 283 | ### Fixed |
| 284 | |
| 285 | - `comparison` check will now ignore `absent(foo)` alert queries without any condition. |
| 286 | |
| 287 | ## v0.3.1 |
| 288 | |
| 289 | ### Added |
| 290 | |
| 291 | - `--offline` flag for `pint ci` command. |
| 292 | |
| 293 | ### Fixed |
| 294 | |
| 295 | - Fixed `template` check panic when alert query had a syntax error. |
| 296 | |
| 297 | ## v0.3.0 |
| 298 | |
| 299 | ### Added |
| 300 | |
| 301 | - `rule` block can now specify `ignore` conditions that have the same syntax as `match` |
| 302 | but will disable `rule` for matching alerting and recording rules #48. |
| 303 | - `match` and `ignore` blocks can now filter alerting and recording rules by name. |
| 304 | `record` will be used as name for recording rules and `alert` for alerting rules. |
| 305 | |
| 306 | ## v0.2.0 |
| 307 | |
| 308 | ### Added |
| 309 | |
| 310 | - `--offline` flag for `pint lint` command. When passed only checks that don't send |
| 311 | any live queries to Prometheus server will be run. |
| 312 | - `template` check will now warn if template if referencing a label that is being |
| 313 | stripped by aggregation. |
| 314 | Example: |
| 315 | |
| 316 | {% raw %} |
| 317 | ```yaml |
| 318 | - alert: Foo |
| 319 | expr: count(up) without(instance) == 0 |
| 320 | annotations: |
| 321 | summary: 'foo is down on {{ $labels.instance }}' |
| 322 | ``` |
| 323 | {% endraw %} |
| 324 | |
| 325 | Would generate a warning since `instance` label is being stripped by `without(instance)`. |
| 326 | |
| 327 | ## v0.1.5 |
| 328 | |
| 329 | ### Fixed |
| 330 | |
| 331 | - Fixed file descriptor leak due to missing file `Close()` #69. |
| 332 | |
| 333 | ## v0.1.4 |
| 334 | |
| 335 | ### Changed |
| 336 | |
| 337 | - Retry queries that error with `query processing would load too many samples into memory` |
| 338 | using a smaller time range. |
| 339 | |
| 340 | ## v0.1.3 |
| 341 | |
| 342 | ### Added |
| 343 | |
| 344 | - `vector_matching` check for finding queries with incorrect `on()` or `ignoring()` |
| 345 | keywords. |
| 346 | |
| 347 | ### Fixed |
| 348 | |
| 349 | - `comparison` check would trigger false positive for rules using `unless` keyword. |
| 350 | |
| 351 | ## v0.1.2 |
| 352 | |
| 353 | ### Fixed |
| 354 | |
| 355 | - `# pint skip/line` place between `# pint skip/begin` and `# pint skip/end` lines would |
| 356 | reset ignore rules causing lines that should be ignored to be parsed. |
| 357 | |
| 358 | ## v0.1.1 |
| 359 | |
| 360 | ### Changed |
| 361 | |
| 362 | - `value` check was replaced by `template`, which covers the same functionality and more. |
| 363 | See [docs](/docs/CONFIGURATION.md#template) for details. |
| 364 | |
