weatherreport not working with debian package
Trying to use weatherreport in couchdb installation form deb package leads to errors
Expected Behavior
$ /opt/couchdb/bin/weatherreport --list
Available diagnostic checks:
custodian Shard safety/liveness checks
disk Data directory permissions and atime
internal_replication Check the number of pending internal replication jobs
ioq Check the total number of active IOQ requests
mem3_sync Check there is a registered mem3_sync process
membership Cluster membership validity
memory_use Measure memory usage
message_queues Check for processes with large mailboxes
node_stats Check useful erlang statistics for diagnostics
nodes_connected Cluster node liveness
process_calls Check for large numbers of processes with the same current/initial call
process_memory Check for processes with high memory usage
safe_to_rebuild Check whether the node can safely be taken out of service
search Check the local search node is responsive
tcp_queues Measure the length of tcp queues in the kernel
Current Behavior
$ /opt/couchdb/bin/weatherreport --list
/usr/bin/env: 'escript': No such file or directory
$ /opt/couchdb/bin/weatherreport --etc /opt/couchdb/etc --list

Possible Solution
Document instructions on how to use weatherreport
Steps to Reproduce (for bugs)
- Install couchdb from deb package on a fresh system
- Try to use weatherreport with above commands

Thanks for your report @sblaisot. Yeah this looks like a bug where we assume there a system-wide Erlang distribution (we expect escript binary to be in PATH) but our Apache CouchDB release is installed in /opt/couch currently.
@nickva having escript in path is not sufficient by itself
$ PATH=/opt/couchdb/bin:/opt/couchdb/erts-12.3.2.10/bin:$PATH
$ /opt/couchdb/bin/weatherreport --etc /opt/couchdb/etc --list
{"init terminating in do_boot",{'cannot get bootfile','no_dot_erlang.boot'}}
init terminating in do_boot ({cannot get bootfile,no_dot_erlang.boot})

Thanks @sblaisot. I imagine we may have to do something similar to what our remsh script does: https://github.com/apache/couchdb/blob/main/rel/overlay/bin/remsh
@nickva do you have any hint on how to run weather-report from deb install?
currently I'm not able to run it.
@sblaisot
I can get it to run but then it can't connect to the node
export PATH="${PATH}:/opt/couchdb/bin:/opt/couchdb/erts-12.3.2.15/bin/"
cd /opt/couchdb/releases/3.3.3
# Point no_dot_erlang.boot to start_clean.boot
sudo ln -s start_clean.boot no_dot_erlang.boot
/opt/couchdb/bin/weatherreport --etc /opt/couchdb/etc/
Is there a solution or fix for this available? The workaround from @baylisscg works for me to and i too can't connect to the local node.
