2020-09-16adds ACLK DISABLE_CLOUD to -W buildinfo (#9936)Timotej S
2020-09-16Added a way to get build configuration info from the agent. (#9913)Austin S. Hemmelgarn
* Add a way to get build configuration info from the agent. This adds a new option to the `-W` switch called 'buildinfo'. When invoked with this argument, Netdata will print it's version, the configure options, and a list of optional features and whether they are enabled or not. This is intended to serve three purposes: * It allows developers to more quickly get an idea of how Netdata was built when triaging bug reports. * It provides an easier way to validate changes to the build system that affect optional features during the development cycle. * It provides an easier way to build CI workflows that validate that building under a given set of constraints results in a feature being enabled or not. The actual implementation is a bit large but overall exceedingly simple, consisting of a set of preprocessor directives to extract optional feature state information from config.h and then a series of printf() calls to actually report this info (which should end up optimized by smart compilers due to all the arguments being compile-time constants). * Added zlib to optional libraries. * Added remaining optional plugins to buildinfo output. * Changed formatting to be more human friendly. * Add remaining optional libraries. * Fix up formatting to be even more human friendly. * Fix typo in buildinfo output. * Remove unused variable. * Fixed spelling of config.h option name. * Update daemon/buildinfo.c Co-authored-by: Markos Fountoulakis <44345837+mfundul@users.noreply.github.com> * Fix option name mismatch for libcrypto. * Update daemon/buildinfo.c Co-authored-by: Markos Fountoulakis <44345837+mfundul@users.noreply.github.com> Co-authored-by: Markos Fountoulakis <44345837+mfundul@users.noreply.github.com>

2020-05-28Added health check functionality to our Docker images. (#9172)Austin S. Hemmelgarn
* Add a `ping` command to netdatacli to check if agent is alive. This provides a way to trivially check if the agent itself appears to be running (namely, the command parser for netdatacli in the agent itself is working and responding), allowing users to check this without having to rely on us continuing to have `help` be a command sent to the agent instead of executing locally. * Add a basic health check to our docke rimages. This adds a relatively basic health checker script to our Docker images. By default it verifies that the `/api/v1/info` endpoint returns a 200 status code. It also supports checking different endpoints or using `netdatacli ping` to check that Netdata is running, all controlled by a new Docker environment variable: `NETDATA_HEALTH_CHECK`. * Avoid unnessecary `chmod` in Dockerfile. Suggested by @prologic. * Fix typo in docs. * Update environment variable name to be more clear. Also add `-L` to `curl` command in health check to follow redirects.
2020-05-21Improve system-info.sh to better handle certain cases when gathering info on ↵Austin S. Hemmelgarn
the system's disk capacity. (#7902) * Remove trailing whitespace in system-info.sh. * Fix handling of APFS on macOS. APFS can have multiple volumes in a single partition, which means that the same functional 'volume' can appear multiple times in the output of `df`. Duplicate lines for such volumes will show the same total size and available space along with a common prefix for the device name. This updates the parsing logic for `df` on macOS to account for this by deduplicating lines in the `df` output that have the same total size, available space, and same normalized device name. This has the potential to incorrectly under-account space in some cases, but the liklihood of that happeing is much less than the certainty of overaccounting space on standard APFS configurations. * Properly handle VirtIO block devices when using /sys. The VirtIO Block device driver uses a dynamically allocated device major number, meaning that we can't trivially match on it. This updates the handling to properly look it up in `/proc/devices` instead of just using the whole dynamic device number range. * Add handling for NVMe block devices in sysfs code. They use dynamic major numbers just like VirtIO Block devices do. * Switch to device major discovery in /proc/devices for all device types. This converts the code to use `/proc/devices` to look up correct device major numbers for block devices taht we treat as disks just like we are already doing for those that have dynamically assigned numbers. This makes the code both more robust and easier to understand and modify. This also excludes some particularly old hardware that we were originally looking for. If needed, we can add in the required device names, but for now it's better to keep the list concise. * Correct handling of device major discovery. We need to strip leading whitespace before calling cut, not after. * Only use /sys/block if we can read /proc/devices. We use `/proc/devices` to do device number lookups that we then use to filter devices under `/sys/block`. As a result, if we can't read `/proc/devices`, then we won't actually parse anything out of `/sys/block` either, so we need to just fall back to parsing `df` output. * Deduplicate `df` output by device name on Linux. This ensures that we properly handle BTRFS subvolumes, counting each actual volume only once. * Use POSIX math expansion instead of awk to sum disk sizes. This avoids the rather annoying habit of AWK of printing integers in scientific notation instead of as exact values. * Correct `sed` options for POSIX complaince. * Fix disk info fetching for macOS> POSIX tools, as found on macOS, lack a number of rather useful filtering and sorting features, so we need to get rather creative with the handling on macOS to make the disk space computation work correctly. This unfortunately makes the calculation a bit less reliable than it would have been had the existing calculations worked correctly, but it's the best I can come up with without making things exponentiall more complicated. * Properly handle sector size when using sysfs.
