ameba-c3's Issues

Extra newline on error messages

Error messages captured from server do carry an extra endline character, so empty lines are displayed between error lines

Metric collection callback

Implement a stats-collector callback, able to append the node to the specified metric configuration files, and call RRDcreate.

implement uuid requesting on standar client

The python client lacks the --request option created for the shell client

Increase verbosity on aupd.conf

Add other registration parameters such as metrics and services to the configuration

Allow url based authentication

Allow authentication bundled in repository url. That is map http://server/path/valid_UUID into authorization for http://server/path (similar to nokia-binaries url for maemo SDK)

Implement profiles

implement registration profiles, to get simpler registering command lines.
Profile should be updatable, so if non existing, only warning will be returned.

timeout exception not captured

urllib2.URLError: <urlopen error (110, 'Connection timed out')>

Nagios services

Extend the nagios callback to register node services (www, mysql, etc).

Bad RHEL packaging for client

The distribution string on the client spec is 'el5', without leading dot

Store option missing for shell client pull

The option --store is not implemented, although utility is probably reduced.

Allow deactivation of callbacks

Although exception handling allows nonworking callbacks to be installed, it is desirable to have some mechanism to select which callbacks must be run, instead of trying to execute all the available ones.

Error in client.loginout()

The loginout function on client library should sleep if a delay is given along session id

shell client does not handle errors

Error conditions are not properly handled.
If a server error happens processing the request, the session below is produced

root@MeshWeb30:/tmp# ./ameba-updater.sh -r -m avgload,netstat,test,meminfo-24 register http://r26936.ovh.net/amebaC3
wget: server returned error: HTTP/1.1 500 Internal Server Error
sed: /tmp/aupd.response.4086: No such file or directory
grep: /tmp/aupd.response.4086: No such file or directory
 root@MeshWeb30:/tmp# 

Allow registration update

Both metrics and services could be modified upon a repeated registration.
This covers modification in the server side stored parameters as well as on the parameters list stored on client configuration

Uncaught error

If the toplevel directory for the fs-backend is not created, an exception is raised.
Probably a similar thing occurs with the bdb backend.

Detect proper values when registering

At least for the C client, giving DISTRO=(null) gets properly registered. Probably even an empty distro name can be registered.

Fix permision of default users

The files for the users created during initialization have owner and permission that disallow them to be edited or managed from the web interface.

Implement configuration reading on client

Implement the ability to read an existing configuration to replace the command line parameters on registering.

Error in client.loginout()

The loginout function should sleep if a wait time is given along the session id

Permission errors on metrics not handled

Default permissions for rrdUtils directories is given to root only. The callback does not handle exception related to this, nor performs proper checks upon loading.

Local configuration not updated upon registering

Seems that when the local aupd.conf exists and is partially populated, it is not update after successful registering. The bug was observed when starting with the file below

[global]
url = http://r26936.ovh.net/amebaC3

[pull]
check-only = True
#check_cmds = apt-get update , ! apt-get -s -y upgrade | grep -q '^Inst\ '
#check_cmds = apt-get update , ! apt-get -s -y upgrade | grep -q \'\^Inst \'
check_cmds = apt-get update , ! apt-get -s -y upgrade | grep -qw ^Inst
#check_cmds = apt-get update , ! apt-get -s -y upgrade | grep -qw Inst
update_cmds = apt-get -y upgrade 

Bug closing for 1.5

Before releasing 1.5 client, the issues below should get closed:

Nagios configs generator

It could be useful to have a command able to recreate nagios configurations from database contents. That means that only the database must be backed up.

Update mode for shell client

Implement package update in the shell script client

Avoid random waits on interactive upgrades

When forcing a pull from the command line, the random wait time is honoured

Create packages

Besides the opkg/deb package, a standard RPM is desirable.

Unhandled timeout en el cliente shell

A transient network related issue seems to show that under some circumstances the shell client in openwrt platforms does replicate multiple times.

The problem will be probably difficult to replicate, but two possible solutions are include a timeout for wget or a more elaborated locking mechanism.

Avoid sending commands to nagios if external commands disabled

If nagios is started whitout external command checking, and the feature is later enabled, nagios refuses to start because the named pipe already exists.
Either we avoid writing to nagios.cmd if not existing, or we create it as a named pipe when needed

Error durante la actualizacion

Por fin he vuelto a pillar el error que habia visto por ahi:

root@ccientifico:~# aupd --force-upgrade --random-wait 1 pull
None <- apt-get --yes upgrade
100 <- apt-get --yes upgrade
Calling loginout with True
ERROR : failed at apt-get --yes upgrade
root@ccientifico:~# echo $?
1

El origen del error no esta claro, pero la actualizacion de paquetes no se realiza.
La actualizacion posterior realizada a mano transcurre sin problemas, y aunque muestra algun warning, devuelve 0 como codigo de retorno.

Nagios callbacks configurability

The nagios callback is not configurable, as everything is included in the code.
To make easy the inclusion of new services, an external storage method must be implemented (filesystem as first choice).
Default templates and the variables to locate nagios resources are also open to be shifted out of the source code, although the requirement is less high.
