We are using worklight 6.0 version. We are using an adapter to accept logs from device and to store in server. The log level is info. But we are getting debug logs with previous timestamps now. What could be the possible reason for this?
I am not sure about the statement regarding timestamps, but if you're getting debug logs in the server that would mean to me that you are not actually sending logs in the correct level. See here: http://www-01.ibm.com/support/knowledgecenter/SSZH4A_6.2.0/com.ibm.worklight.monitor.doc/monitor/c_op_analytics_data_capture.html
If you want to send INFO level logs, set WL.Logger.config({level: "INFO"});
Likewise in the server, set INFO for the following logging options: https://www-01.ibm.com/support/knowledgecenter/SSAW57_8.5.5/com.ibm.websphere.wlp.nd.doc/ae/rwlp_logging.html (whichever one you need):
com.ibm.ws.logging
.console.log.level
com.ibm.ws.logging
.message.file.name

What would be the best way to debug Parse Cloud Code? Currently it's a mess of logging to the console and checking logs. Does anyone have a good workable solution?
During development, you should begin by testing against a local hosted server. I.e., I use VS Code. You can set breakpoints and watch variables for their values. You can set up a tool like ngrok to get a remote URL for your local endpoint so you can test with non-local hosted clients if you'd like.
We also use Slack extensively. We've created our own slack bot, and it has several channels it reports relevant information too, triggered from our parse-server. One of these is a dev error channel. Instead of console.logs, which are hard to sift through and find what you're looking for, we push important information to Slack. We don't switch every single console.log to a slack message, just the important "Hey something went wrong here's the information" messages. This brings them to our attention so we can identify and resolve them way faster. Slack is awesome. I recommend using slack, even on a solo project.
at the moment you can access your Logs using a console.log() or console.error() for functions and all general logs of everything that happens with your app, at Back4App you can access using: Server Settings -> Logs -> Settings -> Server System Log.
Or functions and all logs generated by Parse server, they're: request.log.info() and request.log.error(), at Back4App you can access using: Dashboard -> Logs.
Our ServiceNOW instance recently got upgraded from Eureka to Geneva.
MID Server status became down and the version does not match the Build number in the stats.
I was told that the MID Server will auto upgrade which didn't happened. I am using a proxy server to connect, when I tried communicating with the instance through the server it is working however I assume the service or application installed is not able to communicate with the instance.
I created a new service and it worked perfectly for 1 min however after that the status of it became down.
Then I tried changing the configurations of old services however no good.
Now the services are running fine however in the config file in the mid_sys_id section mid server details not getting populated and the status of the MID Server in the instance is always down.
Do I need to change any properties in the instance?
Since I use proxy server do I need to remove the comment line of the auto upgrade through proxy section or can I leave that blank?
What is the issue here? Why my MID Server is not getting upgraded? Kindly help me.. If possible an explanation with screen shot would be much appreciated.
If you're on Geneva, you should be able to simply go to your MIDServer listing, from inside your instance, click on a MIDServer, and find 'Upgrade MID' in the Related links section. That should start an upgrade for that MID Server. If it fails, there should be an entry in either the ServiceNow logs or the MID Server logs with more information why it failed.
After redeploying a worklight application, some configuration for analytics got lost and I'm trying to configure worklight with analytics again.
The dashboard shows "No data available" for time after the deployment although there are old records displayed for the time before the deployment of the application. So the db was not affected.
I set the wl.analytics.logs.forward property to "true" in worklight.properties;
also I set the wl.analytics.url of the db to be something like:
https://myserver:port/analytics/data
The dashboard is on
https://myserver:port/analytics/console
That is the URL for the analytics server.
Although if I put the db URL in a browser I get something like:
Error 404: java.io.FileNotFoundException: SRVE0190E: File not found: /data
Checked SystemOut.log and SystemErr.log (WAS logs) and I did not see errors there.
Does anybody know which is the XML I need to check in order to validate the configuration is OK for analytics? How could I troubleshoot this problem? Are there other logs I could check?
In the list of environment variables you gave I do not see any for username and password. Try to set:
wl.analytics.password=admin
wl.analytics.username=admin
It would be useful to see a wireshark trace, maybe you are not getting 403s. The Analytics data uploader generally has a small bit of protections and you have the option to keep or remove it.
#patbarron is correct about the multiple WAR files though. You need to send your analytics data to the /analytics-service context. The WAR analytics-service is the WAR that handles all the data processing, querying, etc. The other WAR analytics just handles the console UI.
When testing it might be beneficial to lower the
wl.analytics.queue and wl.analytics.queue.size, those values are for collecting data on the MobileFirst runtime server. Data is collected at the runtime server then sent to the analytics server. The larger these values are generally, the longer it will take to send. There are good to set for production
I am trying show end users maintainence window such as "we are down please try later" and disable the application but my problem is what if my worklight server itself is down and not reachable and i cannot use the feature provided by worklight console,
Is there a way i make my app talk to a different server which returns back the below json data when a app is disabled , can i simulate this behaviour is this possible.
json recieved on access disabled in worklight :-
/*-secure-
{"WL-Authentication-Failure":{"wl_remoteDisableRealm":{"message”:”We are down, Please try again soon","downloadLink":null,"messageType":"BLOCK"}}}*/
I have some conceptual problems with this question.
Typically a production environment (simplified) would not consist of a single server serving your end-users... meaning, there would be a cluster of nodes, each node being a Worklight Server, and this cluster would be behind a load balancer that would direct the incoming requests. And so in a situation where a node is down for maintenance like in your scenario there would still be more servers able to serve - there would be no down time.
And thus at this point your suggestion to simulate a Remote Disable by sending it from another(?) Worklight Server seems not so much the correct path to take (it may even be simply wrong). Have you had this second Worklight Server, why wouldn't it just serve the apps business like usual? See again my first paragraph about clustering.
Now lets assume there is still a downtime, that affects all servers. The application's client logic should be able to handle failed connections to the Worklight Server. In such a case you should handle this in the WL.Client.connect()'s onFailure callback function to display a WL.SimpleDialog that looks just like a Remote Disable's dialog... or perhaps via the initOption.js's onConnectionFailure callback.
Bottom line: you cannot simulate the JSON that is sent back for the wl_RemoteDisable realm; it is part of a larger security mechanism.
Additionally though, perhaps a way to better handle maintenance mode on your server is to have the HTTP server return a specific HTTP status code, check for this code and display a proper message based on the returned HTTP status code.
To check for this code in a simple example:
Note: the getStatus method is available starting MobileFirst Platform Foundation 7.0 (formerly "Worklight").
function wlCommonInit(){
WL.Client.connect({onSuccess:success, onFailure:failure});
}
function success(response) {
// ...
}
function failure(response) {
if (response.getStatus() == "503") {
// site is down for maintenance - display a proper message.
} else if ...
}
While I was trying to start ApacheDS 1.5.7 on windows platform, An Error 04450 occurs and the apacheds-rolling.log contains:
[21:07:27] ERROR [org.apache.directory.shared.ldap.entry.DefaultServerAttribute] - ERR_04450 The value {0} is incorrect, it hasnt been added
[21:07:27] ERROR [org.apache.directory.server.Service] - Cannot start the server : reuseAddress can't be set while the acceptor is bound.
How can i fix this problem? Anybody could help me? many thanks!
The warning log message is a bit misleading, actually this is not a serious issue, the server should be running despite of this warning, this has been fixed a while back in the latest trunk code (which will be released as 2.0 instead of 1.5.8).
According to this post, the dc=example,dc=org context entry is not created by default anymore but no one has updated the documentation to reflect this. I installed 1.5.7 and it looks to me like the partition was created fine, but I'm getting the same error as described above. I suggest installing an older version.
The 2nd error message suggests that the port is already in use. Is there a chance that you already had another ApacheDS process running, or that another program is using the ports?
This isn't a domain controller perchance, is it? If so, the default LDAP ports 389 & 636 are already in use for Active Directory, so you'll need to choose another. However, I believe the defaults for ApacheDS are 10389 (LDAP) and 10636 (LDAPS), in which case they would typically be open on a Windows box.
You can check for processes on the ports with the netstat -abn command, and look through the list for the process listening on port 10389 or whichever custom port you chose.
