## [1.21.0] - 2025-05-08
10+
11+
This release adds several new metrics for tracking flash wear, as well as a new
12+
syslog log source. It also includes a config flag to enable legacy statsd metric
13+
names, and a data retention check to the upload process. For more information on
14+
the new metrics, check out the
15+
[docs](https://docs.memfault.com/docs/linux/introduction).
16+
17+
### Added
18+
19+
- Added metrics for tracking flash wear for mmc block devices like eMMC and SD
20+
cards
21+
- `diskstats/<disk_name>/bytes_written`
22+
- `diskstats/<disk_name>/lifetime_pct`
23+
- `diskstats/<disk_name>/manufacturer_id`
24+
- `diskstats/<disk_name>/name`
25+
- Added syslog as a logs source. This adds support for messages in both RFC5424
26+
and RFC3164 format sent over UDP. This is enabled with the `syslog` feature
27+
which defaults to enabled.
28+
- Added a config flag to enable legacy statsd metric names. This will generate
29+
metrics that follow the format generated by the `collectd` statsd server. This
30+
is a helpful option for people looking to remove `collectd` as a dependency,
31+
but keep the legacy format for metric keys. The config value can be found in
32+
`metrics`->`statsd_server`->`legacy_key_names`.
33+
- Added time-based data filtering: When upgrading multiple devices' visibility
34+
levels, the Memfault backend now tells `memfaultd` to only upload data from
35+
the time of the change forward. This prevents unexpected large data uploads
36+
from device history.
37+
- Added `interface/<interface>/total_bytes/{tx,rx}` metrics. These allow us to
38+
track the total bytes sent over an interface over the course of an hour.
39+
40+
### Changed
41+
42+
- Added intelligent traffic distribution: Device initial connections now include
43+
a random delay (up to 25% of the configured upload interval). This prevents
44+
traffic spikes when many devices connect simultaneously, ensuring smoother
45+
backend performance.
46+
- `ram` and `loop` disks are no longer tracked with diskstats in auto mode.
47+
These are virtual disks, and provide little value when tracking metrics.
