Monitoring in Ganesha?
by Bjorn Leffler
Apart from the counters that you can access through dbus, is there any
other monitoring built into Ganesha?
I'm thinking of adding it with this higher level plan:
- Exporting metrics from Ganesha to Prometheus.
- Aggregate data in Prometheus.
- Display monitoring consoles and graphs with Grafana.
- Package up Prometheus, Grafana and the preconfigured rules/dashboards as
a Docker image.
- This makes it straightforward to deploy monitoring alongside a Gansha
binary.
My rough coding plan for the code is to:
- Add a USE_MONITORING directive to the CMakeLists.txt files.
- Add a build dependency to the Prometheus C client
<https://github.com/digitalocean/prometheus-client-c>.
- Create a src/monitoring directory for the new source files and templates.
- Increment counters and timers throughout the code.
- Use histograms to compute latency percentiles, heatmaps, etc.
Is this a good idea? Any objections or suggestions?
Thanks,
Bjorn

Issue with calling done_cb from a different thread for fsal_read2
by Chakra Divi
Hi all,
I'm working to create an async model in fsal layer for my filesystem. As part of this, called "done_cb" for a read_req from my own thread in fsal layer. This causes hang and nfs4 stopped responding. Here is pseudo code for the read callback. i could see a similar implementation in FSAL_MEM (mem_handle.c) layer
void fsal_read2_cb(void *cbArg, int err) {
struct test_wa *wa = (struct test_wa*)cbArg;
fsal_errors_t fsal_error = posix2fsal_error(err);
struct root_op_context root_op_context;
init_root_op_context(&root_op_context, wa->ctx_export, wa->fsal_export, 0, 0, UNKNOWN_REQUEST);
wa->done_cb(wa->obj_hdl, fsalstat(fsal_error, err), wa->read_arg, wa->caller_arg);
release_root_op_context();
free(wa);
return;
}
Shouldn't we call done_cb from a custom thread ? Can you please let me know if i'm missing something and right way to do this - Thanks for the help
Regards,
Chakra

Change in ...nfs-ganesha[next]: ProxyV3: Pass the *original* credentials to backends.
by Solomon Boulos (GerritHub)

ProxyV3: Pass the *original* credentials to backends.
With manage_gids set to true, op_ctx->creds gets replaced
with a potentially large list (above the 16 limit). We
actually just want to reflect what the client does (while
Ganesha's MDCACHE will do the same manage_gids access test).

Allow host_to_key to return a key that is larger than the host handle
The host_to_key method may add AT MOST FSAL_KEY_EXTRA_BYTES. Callers
of host_to_key MUST allocate this extra space.

by Frank Filz (GerritHub)

CEPH: Introduce host_to_key and fix up use of host handles and handle-key
After clarifying how the various handle forms are used, and noting that
CEPH was missing host_to_key, it's clear that wire_to_host MUST produce
a host handle (without the export_id), not a handle-key. If the handle-key
(with the export_id) is needed, MDCACHE will call host_to_key.
The create_handle method is passed a host handle NOT a handle-key so it
must NOT expect the export_id to be there.
