Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	1. Description of Business and Summary of Significant Accounting Policies Description of Business Basis of Presentation Balance Sheet Classification of Deferred Taxes In the opinion of management, the unaudited condensed consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the financial position, results of operations, comprehensive loss and cash flows for the interim periods, but are not necessarily indicative of the results of operations to be anticipated for the full fiscal year ending March 31, 2016. The condensed consolidated balance sheet as of March 31, 2015 included herein was derived from the audited financial statements as of that date. Initial Public Offering The sale of common stock in the IPO triggered the weighted average anti-dilution provisions set forth in the Company’s amended and restated certificate of incorporation. At the IPO price of $23.00 per share, the per share conversion rate for the Company’s Series F convertible preferred stock into common stock was approximately 1:1.02. The conversion rate for the Company’s Series A, Series B, Series C, Series D, and Series E convertible preferred stock was 1:1. As a result of the IPO, the 24,813,343 shares of the Company’s convertible preferred stock outstanding automatically converted into 24,885,778 shares of the Company’s common stock.

Business Combinations [Abstract]
Business Combination	2. Business Combination Opsmatic, Inc. In October 2015, the Company completed the acquisition of Opsmatic, Inc. (“Opsmatic”), a provider of live-state server configuration monitoring across dynamic cloud infrastructure, pursuant to which the Company acquired all of the capital stock of Opsmatic for $5.5 million in cash, up to 161,116 shares of the Company’s common stock, a portion of which are subject to forfeiture in the event of certain indemnification claims by the Company, and 12,008 restricted stock units (“RSUs”) with fair values of $39.15 per share, resulting in an aggregate purchase price of $12.3 million. Of the total purchase price, $2.5 million was allocated to acquired technology and an immaterial amount to net assets acquired, with the excess $9.8 million of the purchase price over the fair value of net tangible and intangible assets acquired recorded as goodwill. The Company also recognized transaction costs of approximately $0.4 million, which is included in general and administrative expense in its condensed consolidated statements of operations for the nine months ended December 31, 2015. The Opsmatic technology complements the Company’s existing server and infrastructure monitoring capabilities. The acquisition has been accounted for as a business combination under the acquisition method. Goodwill generated from the acquisition is attributable to expected synergies from future growth and potential future monetization opportunities, and is not deductible for tax purposes. Pro forma revenue and results of operations have not been presented because the historical results of Opsmatic were not material to the Company’s condensed consolidated financial statements in any period presented. The acquisition also included an obligation to issue up to 98,115 shares of its common stock, with an aggregate grant date fair value of $3.8 million, to certain employees of Opsmatic, contingent upon their continuous employment with the Company. As such, compensation expense will be recorded on a straight-line basis over the respective service period of 30 months. As of December 31, 2015, 50,079 of these shares were issued, all of which are subject to repurchase by the Company. Few Ducks, S.L. In October 2014, the Company closed the acquisition of Few Ducks, S.L., (“Ducksboard”), a provider of real-time dashboards for tracking business metrics from a broad set of application sources, pursuant to which the Company acquired all of the capital stock of Ducksboard for 121,493 shares of the Company’s common stock, all of which were issued upon the conclusion of the indemnity holdback period, and $2.3 million in cash resulting in an aggregate purchase price of $4.2 million. Of the total purchase price, $2.8 million was allocated to identifiable intangible assets and $0.7 million to net liabilities assumed, with the excess $2.1 million of the purchase price over the fair value of net tangible liabilities assumed and intangible assets acquired recorded as goodwill. The addition of the Ducksboard technology complements the Company’s visualization expertise and the Company believes it will readily expand the sources of data that are available to customers via the Company’s Software Analytics data cloud. The Company accounted for the acquisition of Ducksboard as a purchase of a business. Goodwill generated from the acquisition is attributable to expected synergies from future growth and potential future monetization opportunities, and is not deductible for tax purposes. Pro forma revenue and results of operations have not been presented because the historical results of Ducksboard were not material to the Company’s condensed consolidated financial statements in any period presented. In connection with the acquisition, the Company also agreed to issue up to 128,507 shares of its common stock, with an aggregate grant date fair value of $1.9 million, to certain former employees of Ducksboard, contingent upon their continuous employment with the Company. From the date of acquisition, compensation expense is recorded on a straight-line basis over the respective service period of three years. As of December 31, 2015, 38,566 of these shares were issued.

Fair Value Measurements	3. Fair Value Measurements The following tables present information about the Company’s financial assets measured at fair value on a recurring basis as of December 31, 2015 and March 31, 2015 based on the three-tier fair value hierarchy (in thousands): Fair Value Measurements as of December 31, 2015 Level 1 Level 2 Level 3 Total Description: Money market funds $ 36,117 $ — $ — $ 36,117 Corporate notes and bonds — 25,359 — 25,359 U.S. treasury securities 2,289 — — 2,289 U.S. government agencies — 97,285 — 97,285 Restricted cash - money market funds 8,023 — — 8,023 Total $ 46,429 $ 122,644 $ — $ 169,073 Included in cash and cash equivalents $ 41,945 Included in short-term investments $ 119,105 Included in restricted cash $ 8,023 Fair Value Measurements as of March 31, 2015 Level 1 Level 2 Level 3 Total Description: Money market funds $ 56,455 $ — $ — $ 56,455 Certificates of deposit — 1,800 — 1,800 Commercial paper — 30,288 — 30,288 Corporate notes and bonds — 38,715 — 38,715 U.S. treasury securities 500 — — 500 U.S. government agencies — 33,199 — 33,199 Restricted cash - money market funds 4,623 — — 4,623 Total $ 61,578 $ 104,002 $ — $ 165,580 Included in cash and cash equivalents $ 65,454 Included in short-term investments $ 95,503 Included in restricted cash $ 4,623 There were no transfers between fair value measurement levels during the three and nine months ended December 31, 2015. In September 2015, the Company executed a $3.4 million letter of credit in connection with a lease signed in June 2015. The cash collateralized letter of credit is classified as restricted cash on the condensed consolidated balance sheet as of December 31, 2015. Level 3 instruments in prior periods consisted solely of the Company’s preferred stock warrant liability. Prior to the IPO, outstanding warrants to purchase shares of the Company’s Series A and Series D convertible preferred stock were classified as other liabilities. The initial liability recorded was adjusted for changes in the fair values of the Company’s preferred stock warrants during each reporting period and was recorded as a component of other income (expense), net in the statement of operations. The Company estimated the fair values of these warrants using the Black-Scholes option-pricing model, based on the inputs for the estimated fair value of the underlying convertible preferred stock at the valuation measurement date, the remaining contractual term of the warrant, risk-free interest rates, expected dividend rates and expected volatility of the price of the underlying convertible preferred stock. These estimates were based on subjective assumptions. During the three and nine months ended December 31, 2014, the Company recognized charges in the amount of $0.3 million and $82,000, respectively, which were recorded as other expense in the Company’s condensed consolidated statements of operations. Upon the closing of the IPO in December 2014, the Company ceased recording any further related periodic fair value adjustments. Gross unrealized gains or losses for cash equivalents and available-for-sale marketable securities as of December 31, 2015 and March 31, 2015 were not material. As of December 31, 2015 and March 31, 2015, there were no securities that were in an unrealized loss position for more than 12 months. The following table classifies the Company’s available-for-sale short-term investments by contractual maturities as of December 31, 2015 and March 31, 2015 (in thousands): December 31, March 31, Due in one year $ 92,793 $ 53,287 Due in one to two years 26,312 42,216 Total $ 119,105 $ 95,503 For certain other financial instruments, including accounts receivable, accounts payable and other current liabilities, the carrying amounts approximate their fair value due to the relatively short maturity of these balances.

CA, Inc.’s complaint against the Company claims that certain aspects of the Company’s products infringe certain patents held by CA, Inc. Discovery is complete in the case, and the court has ruled on summary judgment motions filed by both parties. A trial date has not been set as of December 31, 2015. The Company cannot at this time predict the likely outcome of this proceeding or estimate the amount or range of loss or possible loss that may arise from it. The Company has not accrued any loss related to the outcome of this case as of December 31, 2015. In the normal course of business, the Company may agree to indemnify third parties with whom it enters into contractual relationships, including customers, lessors, and parties to other transactions with the Company, with respect to certain matters. The Company has agreed, under certain conditions, to hold these third parties harmless against specified losses, such as those arising from a breach of representations or covenants, other third-party claims that the Company’s products when used for their intended purposes infringe the intellectual property rights of such other third parties, or other claims made against certain parties. To date, the Company has not incurred any costs as a result of such obligations and has not accrued any liabilities related to such obligations in the condensed consolidated financial statements. In addition, the Company indemnifies its officers, directors, and certain key employees while they are serving in good faith in their respective capacities. The Company does not currently believe there is a reasonable possibility that a loss may have been incurred under these indemnification obligations. To date, there have been no claims under any such indemnification provisions.

Income Tax Disclosure [Abstract]
Income Taxes	8. Income Taxes The Company is subject to income tax in the United States as well as other tax jurisdictions in which it conducts business. Earnings from non-U.S. activities are subject to local country income tax. The Company does not provide for federal income taxes on the undistributed earnings of its foreign subsidiaries as such earnings are to be reinvested indefinitely. The Company recorded an income tax provision of $0.1 million and an income tax benefit of $0.1 million for the three months ended December 31, 2015 and 2014, respectively, and an income tax provision of $0.2 million and an income tax benefit of $0.1 million for nine months ended December 31, 2015 and 2014, respectively, related to foreign income taxes and state minimum taxes. Based on the available objective evidence during the three and nine months ended December 31, 2015, the Company believes it is more likely than not that the tax benefits of U.S. losses incurred during the three and nine months ended December 31, 2015 may not be realized. Accordingly, the Company did not record the tax benefits of U.S. losses incurred during the three and nine months ended December 31, 2015. The primary difference between the effective tax rate and the local statutory tax rate relates to the valuation allowance on the Company’s U.S. losses, foreign tax rate differences, and amortization of a deferred charge associated with the intercompany transfer of intellectual property from prior periods. As of December 31, 2015, the total amount of gross unrecognized tax benefits was $2.3 million, all of which would affect the Company’s effective tax rate if recognized before consideration of any valuation allowance. As of December 31, 2015, the Company had an immaterial amount related to the accrual of interest and penalties. During the nine months ended December 31, 2015, the Company’s gross unrecognized tax benefits increased by $0.5 million, none of which would affect the Company’s effective tax rate if recognized. The Company does not have any tax positions as of December 31, 2015 for which it is reasonably possible that the total amount of gross unrecognized tax benefits will significantly increase or decrease within the next 12 months.

Earnings Per Share [Abstract]
Net Loss Per Share	9. Net Loss Per Share Basic loss per share is calculated by dividing net loss by the weighted-average number of common shares outstanding during the period, less shares subject to repurchase, and excludes any dilutive effects of employee share-based awards and warrants. Diluted net loss per common share is computed giving effect to all potential dilutive common shares, including common stock issuable upon exercise of stock options and unvested restricted common stock. As the Company had net losses for each of the three and nine months ended December 31, 2015 and 2014, all potential common shares were determined to be anti-dilutive. The following table sets forth the computation of net loss per share attributable to common stockholders, basic and diluted (in thousands, except per share amounts): Three Months Ended December 31, Nine Months Ended December 31, 2015 2014 2015 2014 Numerator: Net loss $ (18,355 ) $ (15,929 ) $ (48,293 ) $ (35,324 ) Denominator: Weighted average shares used to compute net loss per share attributable to common stockholder, basic and diluted 48,953 22,847 48,001 18,182 Net loss per share—basic and diluted $ (0.37 ) $ (0.70 ) $ (1.01 ) $ (1.94 ) The following outstanding options, unvested shares, warrants, and ESPP shares were excluded (as common stock equivalents) from the computation of diluted net loss per common share for the periods presented as their effect would have been antidilutive (in thousands): As of December 31, 2015 2014 Options to purchase common stock 7,577 9,516 Common stock reserved for issuance in connection with acquisition 90 — Restricted stock units 1,501 669 Warrants — 28 ESPP shares 67 — 9,235 10,213
