How do I use the Grafana client for java to upload dashboards with a time-series filled panel to Grafana?

I am currently comparing time-series. They are stored in InfluxDB. My task is to get two time-series from InfluxDB, compare them and upload a visualization to Grafana. The comparison result would be output to console and the two time-series would be uploaded to Grafana in a dashboard and they should be in the same panel. I am trying to use the grafana-api-java-client found here. My problem is that I can not figure out how to do this with the provided examples and Javadocs. There is not a lot of documentation and the examples don't work properly in my case. I hope that someone has worked with this client and can explain how to properly add two time-series to a panel in a dashboard and upload it.
I will provide what I am doing and then post the examples from the github page of the API.
First of all this is how I am getting my time series:
public List<Double> getTimeSeries(String streetName, String start, String stop) {
//gets the query result
QueryResult queryResult = influxDB.query(new Query(String.format("SELECT value FROM your_measurement WHERE street='%s' " +
"AND time >= '%s' AND time <= '%s'", streetName, start, stop)));
//Gets the values from the query result
List<List<Object>> values = queryResult.getResults().iterator().next().getSeries().iterator().next().getValues();
//Adds the values to a list
List<Double> timeSeries = new ArrayList<>();
for (List<Object> li : values) {
timeSeries.add(Double.valueOf(li.get(1).toString()));
}
return timeSeries;
}
I can convert this list to an array of doubles:
double[] timeSeriesArray = timeSeries.stream().mapToDouble(d -> d).toArray();
The following is the first example. It works properly up until the getDashboard() and deleteDashboard() methods, where I get the error that such a dashboard does not exist, even though it does. I don't know what causes this error. Every new dashboard ends up in the folder "General". The method createDashboard() creates, as expected, an empty dashboard in Grafana.
import com.appnexus.grafana.client.GrafanaClient;
//Setup the client
GrafanaConfiguration grafanaConfiguration =
new GrafanaConfiguration().host("your_grafana_host").apiKey("Bearer your_secret_key");
GrafanaClient grafanaClient = new GrafanaClient(grafanaConfiguration);
//Setup the dashboard
String DASHBOARD_NAME = "new_dashboard";
Dashboard dashboard = new Dashboard()
.title(DASHBOARD_NAME)
.version(0);
GrafanaDashboard grafanaDashboard = new GrafanaDashboard().dashboard(dashboard);
//Make API calls
grafanaClient.createDashboard(grafanaDashboard);
grafanaClient.getDashboard(DASHBOARD_NAME);
grafanaClient.deleteDashboard(DASHBOARD_NAME);
This is the second example. I assume that I have to modify it in order to solve my problem. I had to replace two things to get this example to work, which I will explain with code comments. When executing this code it creates a dashboard with an empty panel. I expected something to be shown on the panel but it is empty and there are no axes.
import com.appnexus.grafana.client.GrafanaClient;
//Setup the client
GrafanaConfiguration grafanaConfiguration =
new GrafanaConfiguration().host("your_grafana_host").apiKey("Bearer your_secret_key");
GrafanaClient grafanaClient = new GrafanaClient(grafanaConfiguration);
//Setup the dashboard
String DASHBOARD_NAME = "new_dashboard";
DashboardPanelTarget dashboardPanelTarget =
new DashboardPanelTarget().refId("getSomeMetric").target("*");
DashboardPanelXAxis dashboardPanelXAxis =
new DashboardPanelXAxis().show(true).mode(DashboardPanelXAxis.Mode.TIME);
DashboardPanelYAxis dashboardPanelYAxis =
new DashboardPanelYAxis().format(DashboardPanelYAxis.Format.SHORT).logBase(1).show(true);
//Datasource is required or alerts cannot be added
DashboardPanel dashboardPanel =
new DashboardPanel()
//This might be where my data has to go but I am not sure.
.targets(new ArrayList<>(Collections.singletonList(dashboardPanelTarget)))
//Had to change DASHBOARD_DATA_SOURCE to a String -> "DASHBOARD_DATA_SOURCE", I assume it's just the name of the datasource.
//.datasource(DASHBOARD_DATA_SOURCE)
.datasource("DASHBOARD_DATA_SOURCE")
.type(DashboardPanel.Type.GRAPH)
.fill(1)
.title(dashboardName)
.linewidth(1)
.lines(true)
.height("300px")
.span(12)
.xaxis(dashboardPanelXAxis)
.yaxes(new ArrayList<>(Arrays.asList(dashboardPanelYAxis, dashboardPanelYAxis)));
DashboardRow dashboardRow =
new DashboardRow()
.collapse(false)
.panels(new ArrayList<>(Collections.singletonList(dashboardPanel)));
Dashboard dashboard =
new Dashboard()
.title(dashboardName)
.schemaVersion(1)
.rows(new ArrayList<>(Collections.singletonList(dashboardRow)));
DashboardMeta dashboardMeta = new DashboardMeta().canSave(true).slug(dashboardName);
GrafanaDashboard grafanaDashboard =
new GrafanaDashboard().meta(dashboardMeta).dashboard(dashboard);
//create new dashboard
//Had to change createDashboardTest() to createDashboard(), because createDashboardTest() doesn't seem to exist
//DashboardMeta createdDashboardMeta = createDashboardTest(grafanaDashboard);
DashboardMeta createdDashboardMeta = createDashboard(grafanaDashboard);

ResearchStack InformedConsent ConsentVisualStep deprecated method problem

I am currently building an Android app using ResearchStack to conduct studies. It is the Android version of ResearchKit. Maybe someone with experience in ResearchKit can also help me. I've used the following example to adapt it to my needs.
https://www.raywenderlich.com/637-researchstack-tutorial-getting-started
The following method is meanwhile deprecated.
visualStep.setNextButtonString(getString(R.string.rsb_next));
Find this line of code outcommented in the example below.
If I am not using this line of code, there is no text shown in the bottom bar where you usually find a "next"-text indicating where to click to continue. Clicking the bottom right corner still causes to go to the next page.
Can anyone help me how to add a text to this?
Tanks!
private List<Step> createConsentSteps(ConsentDocument document) {
List<Step> steps = new ArrayList<>();
for (ConsentSection section: document.getSections()) {
ConsentVisualStep visualStep = new ConsentVisualStep(section.getType().toString());
visualStep.setSection(section);
//visualStep.setNextButtonString(getString(R.string.rsb_next)); //--> deprecated
steps.add(visualStep);
}
ConsentDocumentStep documentStep = new ConsentDocumentStep("consent_doc");
documentStep.setConsentHTML(document.getHtmlReviewContent());
documentStep.setConfirmMessage(getString(R.string.rsb_consent_review_reason));
steps.add(documentStep);
ConsentSignature signature = document.getSignature(0);
if (signature.requiresName()) {
TextAnswerFormat format = new TextAnswerFormat();
format.setIsMultipleLines(false);
QuestionStep fullName = new QuestionStep("consent_name_step", "Please enter your full name",
format);
fullName.setPlaceholder("Full name");
fullName.setOptional(false);
steps.add(fullName);
}
if (signature.requiresSignatureImage()) {
ConsentSignatureStep signatureStep = new ConsentSignatureStep("signature_step");
signatureStep.setTitle(getString(R.string.rsb_consent_signature_title));
signatureStep.setText(getString(R.string.rsb_consent_signature_instruction));
signatureStep.setOptional(false);
signatureStep.setStepLayoutClass(ConsentSignatureStepLayout.class);
steps.add(signatureStep);
}
return steps;
}

How to fetch RTC work item change sets using plain java api?

I am trying to fetch the changes using below code but every time it returns null. I don't know what is wrong with this code.
ILinkManager fLinkManager = (ILinkManager) repo.getClientLibrary(ILinkManager.class);
IReferenceFactory fReferenceFactory = fLinkManager.referenceFactory();
IReference reference = fReferenceFactory.createReferenceToItem(workItem.getItemHandle());
ILinkQueryPage page = fLinkManager.findLinksByTarget("com.ibm.team.filesystem.workitems.change_set", reference,
monitor);
ILinkCollection linkCollection = page.getAllLinksFromHereOn();
Collection<ILink> links = linkCollection.getLinksById("com.ibm.team.filesystem.workitems.change_set");

WebDriver is unable to perform click on an input element having onclick=function1() as an attribute

I am using Web driver 2.31 with Java. It seems the web driver is unable to perform click action on an input element having onclick() attribute.
The input element I need to perform click action on is having the following attributes - id (which is a random generated number), class, type=button, onclick, onmouseout, onmouseover, title and value.
I'm able to fetch the values of title and value attributes which means that the web driver is able to recognize the input element but is not able to perform click action on it.
I have tried with the following:
webdriver.findElement(By.xpath("xpath for the input")).click()
webdriver.findElement(By.xpath("xpath for the input")).sendKeys(Keys.ENTER);
new Actions(webdriver).moveToElement(webdriver.findElement(By.xpath("xpath for the input"))).click().perform();
None of the above options are working.

Do you get any exceptions from element.click()? It it enabled and visible? One of the problems we had was that WebDriver didn't handle position:static elements correctly, so during playback it would cover the button (and you won't see it on screenshot) and it would throw exception "Element is not clickable at point".
We had similar problem with element and had following code that did work sometimes (but also not 100% of times):
element.click();
if("button".equals(tagName)) {
if(element.isEnabled() && element.isDisplayed())
element.sendKeys(Keys.ENTER);
}
But the problem disappeared itself after upgrading WebDriver and we removed sendKeys(ENTER), also it was working fine in 2.29.0.

I faced exactly same problem in my project. The issue was not to locate the element but the onClick() event was not firing.
Then i found out that something else was there which stopped from the event to fire. I had used java script to enable the date picker box & did this,
((JavascriptExecutor)driver).executeScript ("document.getElementById('txtOriginDate').removeAttribute('readonly',0);");
WebElement originDateBox= driver.findElement(By.xpath(prop.getProperty("originDateBox")));
originDateBox.clear();
originDateBox.sendKeys("9-Dec-2014"); //Enter date
Developer designed this in such a way that if you don't use date picker to select date, a specific variable was not set. Which eventually made the **onclick event not to fire.
The date picker code was something like this,
var jsoncustdate = "";
var jsonorigindate = "";
function onSelectCalender( StrDt, obj )
{
if ( !varReadonly ) {
if ( $( "#txtCustDescisionDate" ).attr( "IsDisable" ) == "FALSE" )
{
if ( obj.id == "txtCustDescisionDate" )
{
custobjDt = new Date( obj.selectedYear, obj.selectedMonth,obj.selectedDay, 0, 0, 0, 0 );
jsoncustdate = custobjDt.getTime();
jsoncustdate = "\/Date(" + jsoncustdate + ")\/";
DisabledBtnStage();
// $("#txtFromDate").datepicker("option", "maxDate", objDt);
}
if ( obj.id == "txtOriginDate" )
{
var objDt = new Date( obj.selectedYear, obj.selectedMonth,obj.selectedDay,0, 0,0,0 );
jsonorigindate = objDt.getTime();
jsonorigindate = "\/Date(" + jsonorigindate + ")\/";
DisabledBtnStage();
// $("#txtToDate").datepicker("option", "minDate", objDt);
}
}
elogCommon.CheckMandatory();
}
}
I finally used date picker in normal way & the event fired smoothly.
I hope this answer will help . .cheers !!!

How do I save a value into a custom field in JIRA programmatically?

I've spent days trying to find out how to save or update a value into a CustomField programmatically and finally found out how it's done. So I'll make this a question and then answer it as I would have loved to have this question and answer.
There is conflicting documentation on how to save or update a value for a Custom Field in JIRA. I was using:
customField.setCustomFieldValue(CustomField, value);
This does not save the value into the database but it does update the value as far as I can tell. It's only useful if you are using the CustomField further down in a Workflow Post Function transition for example.
I'm using Jira 4.3.2.
How do I persist the the CustomFields value into the JIRA database?

Ok, this is how I'm successfully updating and saving the CustomField value into the JIRA db.
Comments welcome...
private void saveValue(MutableIssue issue, String valueToSave, CustomField
customField) throws FieldLayoutStorageException {
issue.setCustomFieldValue(customField, valueToSave);
Map<String, ModifiedValue> modifiedFields = issue.getModifiedFields();
FieldLayoutItem fieldLayoutItem =
ComponentManager.getInstance().getFieldLayoutManager().getFieldLayout(issue).getFieldLayoutItem(
customField);
DefaultIssueChangeHolder issueChangeHolder = new DefaultIssueChangeHolder();
final ModifiedValue modifiedValue = (ModifiedValue) modifiedFields.get(customField.getId());
customField.updateValue(fieldLayoutItem, issue, modifiedValue, issueChangeHolder);
}

Here is how I do it (for a custom field I programmatically store a random UUID in):
CustomField cfHash = customFieldManager.getCustomFieldObjectByName(...);
IssueChangeHolder changeHolder = new DefaultIssueChangeHolder();
try {
Object newHashValue = java.util.UUID.randomUUID().toString();
Object oldHashValue = issue.getCustomFieldValue(cfHash);
issue.setCustomFieldValue(cfHash, newHashValue);
cfHash.updateValue(null, issue, new ModifiedValue(oldHashValue, newHashValue), changeHolder);
...
More or less the same as you but with another way to get the ModifiedValue-Object.

Here a solution that works for me in JIRA 6.4.7 to update a custom field value. Actually Im updating a single select field, therefore I have to get the Option for it:
MutableIssue issue = issueManager.getIssueByCurrentKey(issueKey);
FieldConfig relevantConfig = customField.getRelevantConfig(issue);
// if you use a text field use String. or double for numeric
Option optionForValue = optionsManager.getOptions(relevantConfig).getOptionForValue(option, null);
issue.setCustomFieldValue(customField,optionForValue);
Map<String, ModifiedValue> modifiedFields = issue.getModifiedFields();
FieldLayoutItem fieldLayoutItem =
fieldLayoutManager.getFieldLayout(issue).getFieldLayoutItem(customField);
DefaultIssueChangeHolder issueChangeHolder = new DefaultIssueChangeHolder();
final ModifiedValue modifiedValue = modifiedFields.get(customField.getId());
customField.updateValue(fieldLayoutItem, issue, modifiedValue, issueChangeHolder);

I had the same issue and had it resolved using this plugin, fyi=)
