| # Change Log | ||
|
|
||
| [Releases](https://github.com/NetApp/harvest/releases) | ||
|
|
||
| ## 21.05.0 / 2021-05-20 | ||
| **IMPORTANT** v21.05 increased Harvest's out-of-the-box security posture - self-signed certificates are rejected by default. You have two options: | ||
|
|
||
| 1. [Setup client certificates for each cluster](https://github.com/NetApp/harvest-private/blob/main/cmd/collectors/zapi/README.md) | ||
| 2. Disable the TLS check in Harvest. To disable, you need to edit `harvest.yml` and add `use_insecure_tls=true` to each poller or add it to the `Defaults` section. Doing so tells Harvest to ignore invalid TLS certificates. | ||
|
|
||
| **IMPORTANT** RPM and Debian packages will be deprecated in the future, replaced with Docker and native packages. | ||
|
|
||
| **IMPORTANT** Harvest 1.6 is end of support. We recommend you upgrade to Harvest 21.05 to take advantage of the improvements. | ||
|
|
||
| Changes since rc2 | ||
| ### Fixes | ||
| - Log mistyped exporter names and continue, instead of stopping | ||
| - `harvest grafana` should work with custom `harvest.yml` files passed via `--config` | ||
| - Harvest will try harder to stop pollers when they're stuck | ||
| - Add Grafana version check to ensure Harvest can talk to a supported version of Grafana | ||
| - Normalize rate counter calculations - improves latency values | ||
| - Workload latency calculations improved by using related objects operations | ||
| - Make cli flags consistent across programs and subcommands | ||
| - Reduce aggressive logging; if first object has fatal errors, abort to avoid repetitive errors | ||
| - Throw error when use_insecure_tls is false and there are no certificates setup for the cluster | ||
| - Harvest status fails to print port number after restart | ||
| - RPM install should create required directories | ||
| - Collector now warns if it falls behind schedule | ||
| - package.sh fails without internet connection | ||
|
|
||
| ### Enhancements | ||
| - Add new exporter for InfluxDB | ||
| - Add native install package | ||
| - Add ARCHITECTURE.md and improve overall documentation | ||
| - Use systemd harvest.service on RPM and Debian installs to manage Harvest | ||
| - Add runtime profiling support - off by default, enabled with `--profiling` flag. See `harvest start --help` for details | ||
| - Document how to use ONTAP client certificates for password-less polling | ||
| - Add per-poller Prometheus end-point support with `promPort` | ||
| - The release, commit and build date information are baked into the release executables | ||
| - You can pick a subset of pollers to manage by passing the name of the poller to harvest. e.g. `harvest start|stop|restart POLLERS` | ||
|
|
||
| ## rc2 | ||
|
|
||
| ### Fixes | ||
| - RPM package should create Harvest user and group | ||
| - Fixed many bugs (and possibly created new ones) | ||
| - Don't restart pollers without stopping them first | ||
| - Improve XML parse time by changing ZAPI collectors to request less data from ONTAP | ||
| - Fixed race condition in the Prometheus exporter (thanks to Yann Bizeul) | ||
| - Fixed non-portable function calls that would cause Harvest to crash on ARM architectures | ||
|
|
||
| ### Enhancements | ||
| - Add Debian package | ||
| - Improved metric architecture, eliminated race conditions in matrix data structure. This paves the way for other developers to create custom collectors | ||
| - Matrix can be manipulated by collectors and plugins safely | ||
| - Size of the matrix can be changed dynamically | ||
| - Label data is collected (in early versions, at least one numeric metric was required) | ||
| - [New plugin architecture](cmd/poller/plugin/README.md) - creating new plugins is easier and existing plugins made more generic | ||
| - You can use built-in plugins by adding rules to a collector's template. RC2 includes two built-in plugins: | ||
| - **Aggregator**: Aggregates metrics for a given label, e.g. volume data can be used to create an aggregation at the node or SVM-level | ||
| - **LabelAgent**: Defines rules for rewriting instance labels, creating new labels or create ignore-lists based on regular expressions | ||
| ## rc1 | ||
|
|
||
| **IMPORTANT** Harvest has been rewritten in Go | ||
|
|
||
| **IMPORTANT** Harvest no longer gathers data from AIQ Unified Manager. An install of AIQ.UM is not required. | ||
|
|
||
| ### Fixes | ||
|
|
||
| ### Enhancements | ||
| - RPM installation now conforms to a more standard Linux filesystem layout - needed to support container deployments | ||
| - Unified Grafana dashboards for cDOT and 7-mode systems | ||
| - Early release of `harvest config` tool to help you edit your `harvest.yml` file | ||
| - Add ZAPI collectors for performance, capacity and hardware metrics - gather directly from ONTAP | ||
| - Add new exporter for Prometheus | ||
| - Add plugin for Prometheus alert manager integration |
